Blues rock acts that pioneered the sound included Cream, The Jimi Hendrix Experience, and The Jeff Beck Group. Cream, in songs like "I Feel Free" (1966) combined blues rock with pop and psychedelia, particularly in the riffs and guitar solos of Eric Clapton. Jimi Hendrix produced a form of blues-influenced psychedelic rock, which combined elements of jazz, blues and rock and roll. From 1967 Jeff Beck brought lead guitar to new heights of technical virtuosity and moved blues rock in the direction of heavy rock with his band, The Jeff Beck Group. Dave Davies of The Kinks, Keith Richards of The Rolling Stones, Pete Townshend of The Who, Hendrix, Clapton and Beck all pioneered the use of new guitar effects like phasing, feedback and distortion. The Beatles began producing songs in the new hard rock style beginning with the White Album in 1968 and, with the track "Helter Skelter", attempted to create a greater level of noise than the Who. Stephen Thomas Erlewine of AllMusic has described the "proto-metal roar" of "Helter Skelter," while Ian MacDonald argued that "their attempts at emulating the heavy style were without exception embarrassing."

In the United States, macabre-rock pioneer Alice Cooper achieved mainstream success with the top ten album School's Out (1972). In the following year blues rockers ZZ Top released their classic album Tres Hombres and Aerosmith produced their eponymous début, as did Southern rockers Lynyrd Skynyrd and proto-punk outfit New York Dolls, demonstrating the diverse directions being pursued in the genre. Montrose, including the instrumental talent of Ronnie Montrose and vocals of Sammy Hagar and arguably the first all American hard rock band to challenge the British dominance of the genre, released their first album in 1973. Kiss built on the theatrics of Alice Cooper and the look of the New York Dolls to produce a unique band persona, achieving their commercial breakthrough with the double live album Alive! in 1975 and helping to take hard rock into the stadium rock era. In the mid-1970s Aerosmith achieved their commercial and artistic breakthrough with Toys in the Attic (1975), which reached number 11 in the American album chart, and Rocks (1976), which peaked at number three. Blue Öyster Cult, formed in the late 60s, picked up on some of the elements introduced by Black Sabbath with their breakthrough live gold album On Your Feet or on Your Knees (1975), followed by their first platinum album, Agents of Fortune (1976), containing the hit single "(Don't Fear) The Reaper", which reached number 12 on the Billboard charts. Journey released their eponymous debut in 1975 and the next year Boston released their highly successful début album. In the same year, hard rock bands featuring women saw commercial success as Heart released Dreamboat Annie and The Runaways débuted with their self-titled album. While Heart had a more folk-oriented hard rock sound, the Runaways leaned more towards a mix of punk-influenced music and hard rock. The Amboy Dukes, having emerged from the Detroit garage rock scene and most famous for their Top 20 psychedelic hit "Journey to the Center of the Mind" (1968), were dissolved by their guitarist Ted Nugent, who embarked on a solo career that resulted in four successive multi-platinum albums between Ted Nugent (1975) and his best selling Double Live Gonzo (1978).

Established bands made something of a comeback in the mid-1980s. After an 8-year separation, Deep Purple returned with the classic Machine Head line-up to produce Perfect Strangers (1984), which reached number five in the UK, hit the top five in five other countries, and was a platinum-seller in the US. After somewhat slower sales of its fourth album, Fair Warning, Van Halen rebounded with the Top 3 album Diver Down in 1982, then reached their commercial pinnacle with 1984. It reached number two on the Billboard album chart and provided the track "Jump", which reached number one on the singles chart and remained there for several weeks. Heart, after floundering during the first half of the decade, made a comeback with their eponymous ninth studio album which hit number one and contained four Top 10 singles including their first number one hit. The new medium of video channels was used with considerable success by bands formed in previous decades. Among the first were ZZ Top, who mixed hard blues rock with new wave music to produce a series of highly successful singles, beginning with "Gimme All Your Lovin'" (1983), which helped their albums Eliminator (1983) and Afterburner (1985) achieve diamond and multi-platinum status respectively. Others found renewed success in the singles charts with power ballads, including REO Speedwagon with "Keep on Loving You" (1980) and "Can't Fight This Feeling" (1984), Journey with "Don't Stop Believin'" (1981) and "Open Arms" (1982), Foreigner's "I Want to Know What Love Is", Scorpions' "Still Loving You" (both from 1984), Heart’s "What About Love" (1985) and "These Dreams" (1986), and Boston's "Amanda" (1986).

In the new commercial climate glam metal bands like Europe, Ratt, White Lion and Cinderella broke up, Whitesnake went on hiatus in 1991, and while many of these bands would re-unite again in the late 1990s or early 2000s, they never reached the commercial success they saw in the 1980s or early 1990s. Other bands such as Mötley Crüe and Poison saw personnel changes which impacted those bands' commercial viability during the decade. In 1995 Van Halen released Balance, a multi-platinum seller that would be the band's last with Sammy Hagar on vocals. In 1996 David Lee Roth returned briefly and his replacement, former Extreme singer Gary Cherone, was fired soon after the release of the commercially unsuccessful 1998 album Van Halen III and Van Halen would not tour or record again until 2004. Guns N' Roses' original lineup was whittled away throughout the decade. Drummer Steven Adler was fired in 1990, guitarist Izzy Stradlin left in late 1991 after recording Use Your Illusion I and II with the band. Tensions between the other band members and lead singer Axl Rose continued after the release of the 1993 covers album The Spaghetti Incident? Guitarist Slash left in 1996, followed by bassist Duff McKagan in 1997. Axl Rose, the only original member, worked with a constantly changing lineup in recording an album that would take over fifteen years to complete.

In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.

Question: By the late 60s, what term was synonymous with hard rock?
Answer: heavy metal

Question: What heavy metal group introduced darker themes to the music?
Answer: Black Sabbath

Question: What genre was an influence on extreme metal in the 1980s?
Answer: hardcore punk

Question: Hard rock is differentiated from heavy metal by containing more of an influence of what genre?
Answer: bluesy

Question: In heavy metal, riffs typically form what element of a song?
Answer: stand-alone melodies

By the end of the decade a distinct genre of hard rock was emerging with bands like Led Zeppelin, who mixed the music of early rock bands with a more hard-edged form of blues rock and acid rock on their first two albums Led Zeppelin (1969) and Led Zeppelin II (1969), and Deep Purple, who began as a progressive rock group but achieved their commercial breakthrough with their fourth and distinctively heavier album, In Rock (1970). Also significant was Black Sabbath's Paranoid (1970), which combined guitar riffs with dissonance and more explicit references to the occult and elements of Gothic horror. All three of these bands have been seen as pivotal in the development of heavy metal, but where metal further accentuated the intensity of the music, with bands like Judas Priest following Sabbath's lead into territory that was often "darker and more menacing", hard rock tended to continue to remain the more exuberant, good-time music.

Question: Led Zeppelin's first two albums both came out in what year?
Answer: 1969

Question: What was the title of Deep Purple's hard rock 1970 album?
Answer: In Rock

With the rise of disco in the US and punk rock in the UK, hard rock's mainstream dominance was rivalled toward the later part of the decade. Disco appealed to a more diverse group of people and punk seemed to take over the rebellious role that hard rock once held. Early punk bands like The Ramones explicitly rebelled against the drum solos and extended guitar solos that characterised stadium rock, with almost all of their songs clocking in around two minutes with no guitar solos. However, new rock acts continued to emerge and record sales remained high into the 1980s. 1977 saw the début and rise to stardom of Foreigner, who went on to release several platinum albums through to the mid-1980s. Midwestern groups like Kansas, REO Speedwagon and Styx helped further cement heavy rock in the Midwest as a form of stadium rock. In 1978, Van Halen emerged from the Los Angeles music scene with a sound based around the skills of lead guitarist Eddie Van Halen. He popularised a guitar-playing technique of two-handed hammer-ons and pull-offs called tapping, showcased on the song "Eruption" from the album Van Halen, which was highly influential in re-establishing hard rock as a popular genre after the punk and disco explosion, while also redefining and elevating the role of electric guitar.

Question: What two genres made inroads on hard rock in the 1970s?
Answer: disco in the US and punk rock in the UK

Question: What punk band's songs rarely exceeded two minutes in length?
Answer: The Ramones

Established acts benefited from the new commercial climate, with Whitesnake's self-titled album (1987) selling over 17 million copies, outperforming anything in Coverdale's or Deep Purple's catalogue before or since. It featured the rock anthem "Here I Go Again '87" as one of 4 UK top 20 singles. The follow-up Slip of the Tongue (1989) went platinum, but according to critics Steve Erlwine and Greg Prato, "it was a considerable disappointment after the across-the-board success of Whitesnake". Aerosmith's comeback album Permanent Vacation (1987) would begin a decade long revival of their popularity. Crazy Nights (1987) by Kiss was the band's highest charting release in the US since 1979 and the highest of their career in the UK. Mötley Crüe with Girls, Girls, Girls (1987) continued their commercial success and Def Leppard with Hysteria (1987) hit their commercial peak, the latter producing seven hit singles (a record for a hard rock act). Guns N' Roses released the best-selling début of all time, Appetite for Destruction (1987). With a "grittier" and "rawer" sound than most glam metal, it produced three top 10 hits, including the number one "Sweet Child O' Mine". Some of the glam rock bands that formed in the mid-1980s, such as White Lion and Cinderella experienced their biggest success during this period with their respective albums Pride (1987) and Long Cold Winter (1988) both going multi-platinum and launching a series of hit singles. In the last years of the decade, the most notable successes were New Jersey (1988) by Bon Jovi, OU812 (1988) by Van Halen, Open Up and Say... Ahh! (1988) by Poison, Pump (1989) by Aerosmith, and Mötley Crüe's most commercially successful album Dr. Feelgood (1989). New Jersey spawned five Top 10 singles, a record for a hard rock act. In 1988 from 25 June to 5 November, the number one spot on the Billboard 200 album chart was held by a hard rock album for 18 out of 20 consecutive weeks; the albums were OU812, Hysteria, Appetite for Destruction, and New Jersey. A final wave of glam rock bands arrived in the late 1980s, and experienced success with multi-platinum albums and hit singles from 1989 until the early 1990s, among them Extreme, Warrant Slaughter and FireHouse. Skid Row also released their eponymous début (1989), reaching number six on the Billboard 200, but they were to be one of the last major bands that emerged in the glam rock era.

A few hard rock bands from the 1970s and 1980s managed to sustain highly successful recording careers. Bon Jovi were still able to achieve a commercial hit with "It's My Life" from their double platinum-certified album Crush (2000). and AC/DC released the platinum-certified Stiff Upper Lip (2000) Aerosmith released a number two platinum album, Just Push Play (2001), which saw the band foray further into pop with the Top 10 hit "Jaded", and a blues cover album, Honkin' on Bobo, which reached number five in 2004. Heart achieved their first Top 10 album since the early 90s with Red Velvet Car in 2010, becoming the first female-led hard rock band to earn Top 10 albums spanning five decades. There were reunions and subsequent tours from Van Halen (with Hagar in 2004 and then Roth in 2007), The Who (delayed in 2002 by the death of bassist John Entwistle until 2006) and Black Sabbath (with Osbourne 1997–2006 and Dio 2006–2010) and even a one off performance by Led Zeppelin (2007), renewing the interest in previous eras. Additionally, hard rock supergroups, such as Audioslave (with former members of Rage Against the Machine and Soundgarden) and Velvet Revolver (with former members of Guns N' Roses, punk band Wasted Youth and Stone Temple Pilots singer Scott Weiland), emerged and experienced some success. However, these bands were short-lived, ending in 2007 and 2008, respectively. The long awaited Guns N' Roses album Chinese Democracy was finally released in 2008, but only went platinum and failed to come close to the success of the band's late 1980s and early 1990s material. More successfully, AC/DC released the double platinum-certified Black Ice (2008). Bon Jovi continued to enjoy success, branching into country music with "Who Says You Can't Go Home", which reached number one on the Hot Country Singles chart in 2006, and the rock/country album Lost Highway, which reached number one in 2007. In 2009, Bon Jovi released another number one album, The Circle, which marked a return to their hard rock sound.

Title: Great_Plains

The term "Great Plains", for the region west of about the 96th or 98th meridian and east of the Rocky Mountains, was not generally used before the early 20th century. Nevin Fenneman's 1916 study, Physiographic Subdivision of the United States, brought the term Great Plains into more widespread usage. Before that the region was almost invariably called the High Plains, in contrast to the lower Prairie Plains of the Midwestern states. Today the term "High Plains" is used for a subregion of the Great Plains.

Much of the Great Plains became open range, or rangeland where cattle roamed free, hosting ranching operations where anyone was theoretically free to run cattle. In the spring and fall, ranchers held roundups where their cowboys branded new calves, treated animals and sorted the cattle for sale. Such ranching began in Texas and gradually moved northward. In 1866-95, cowboys herded 10 million cattle north to rail heads such as Dodge City, Kansas and Ogallala, Nebraska; from there, cattle were shipped eastward.

Question: what type of land is much of the great plans?
Answer: open range

Question: when did ranchers usually have a cattle round up?
Answer: spring and fall

Question: in a cattle round up, what did ranchers do to the new calves?

With the arrival of Francisco Vázquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542. In that same time period, Hernando de Soto crossed a west-northwest direction in what is now Oklahoma and Texas. Today this is known as the De Soto Trail. The Spanish thought the Great Plains were the location of the mythological Quivira and Cíbola, a place said to be rich in gold.

The 100th meridian roughly corresponds with the line that divides the Great Plains into an area that receive 20 inches (510 millimetres) or more of rainfall per year and an area that receives less than 20 in (510 mm). In this context, the High Plains, as well as Southern Alberta, south-western Saskatchewan and Eastern Montana are mainly semi hot steppe land and are generally characterised by rangeland or marginal farmland. The region (especially the High Plains) is periodically subjected to extended periods of drought; high winds in the region may then generate devastating dust storms. The eastern Great Plains near the eastern boundary falls in the humid subtropical climate zone in the southern areas, and the northern and central areas fall in the humid continental climate.

Question: what is the name of the line that divides the great plains?
Answer: The 100th meridian

Question: about how much rainfall does the great plains get per year?
Answer: 20 inches

After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.

Question: after about what year did railroads bring hunters to the great plains?
