Question: The performer of Take It So Hard is the guitarist of what band?

full_context: Document 1: Hard rock: The roots of hard rock can be traced back to the 1950s, particularly electric blues, which laid the foundations for key elements such as a rough declamatory vocal style, heavy guitar riffs, string-bending blues-scale guitar solos, strong beat, thick riff-laden texture, and posturing performances. Electric blues guitarists began experimenting with hard rock elements such as driving rhythms, distorted guitar solos and power chords in the 1950s, evident in the work of Memphis blues guitarists such as Joe Hill Louis, Willie Johnson, and particularly Pat Hare, who captured a "grittier, nastier, more ferocious electric guitar sound" on records such as James Cotton's "Cotton Crop Blues" (1954). Other antecedents include Link Wray's instrumental "Rumble" in 1958, and the surf rock instrumentals of Dick Dale, such as "Let's Go Trippin'" (1961) and "Misirlou" (1962).
Document 2: It's a Hard Life: "It's a Hard Life" is a song by the British rock band Queen, written by lead singer Freddie Mercury. It was featured on their 1984 album "The Works", and it was the third single from that album. It reached number 6 in the UK Singles Chart and was their third consecutive Top 10 single from the album. It also reached number 2 in Ireland and number 20 in the Netherlands. It also came 19th on a poll, The Nation's Favourite Queen Song broadcast on ITV on Tuesday 11 November 2014.
Document 3: Marshall Bluesbreaker: The Bluesbreaker, which derives its nickname from being used by Eric Clapton with John Mayall & The Bluesbreakers, is credited with delivering "the sound that launched British blues-rock in the mid-1960s." It was Marshall's first combo amplifier, and was described as "arguably the most important [amplifier] in the company's history" and "the definitive rock amplifier."
Document 4: Take It Easy: ``Take It Easy ''is a song written by Jackson Browne and Glenn Frey, and recorded by the Eagles with Frey singing lead vocals. It was the band's first single, released on May 1, 1972. It peaked at No. 12 on the July 22, 1972 Billboard Hot 100 chart. It also was the opening track on the band's debut album Eagles and it has become one of their signature songs, included on all of their live and compilation albums. It is listed as one of The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll.
Document 5: Take It to the Limit (Eagles song): The song was written by Eagles' members Randy Meisner, Don Henley and Glenn Frey. Meisner, who sang lead on it, says the song began as his solo composition. As it remained unfinished when time came for the One of These Nights album to be recorded, Henley and Frey assisted Meisner in completing it. Meisner's performance of the song was popular with the audience in Eagles' concerts, but disputes over his reluctance to perform it would also directly lead to Meisner's departure from the band.
Document 6: The Beatles: The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as ``Beatlemania ''; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's development into an art form and came to be perceived as an embodiment of the ideals shared by the counterculture of the 1960s.
Document 7: Hard rock: In the 1960s, American and British blues and rock bands began to modify rock and roll by adding harder sounds, heavier guitar riffs, bombastic drumming, and louder vocals, from electric blues. Early forms of hard rock can be heard in the work of Chicago blues musicians Elmore James, Muddy Waters, and Howlin' Wolf, The Kingsmen's version of "Louie Louie" (1963) which made it a garage rock standard, and the songs of rhythm and blues influenced British Invasion acts, including "You Really Got Me" by The Kinks (1964), "My Generation" by The Who (1965), "Shapes of Things" (1966) by The Yardbirds and "(I Can't Get No) Satisfaction" (1965) by The Rolling Stones. From the late 1960s, it became common to divide mainstream rock music that emerged from psychedelia into soft and hard rock. Soft rock was often derived from folk rock, using acoustic instruments and putting more emphasis on melody and harmonies. In contrast, hard rock was most often derived from blues rock and was played louder and with more intensity.
Document 8: Hard rock: In the early 1970s the Rolling Stones developed their hard rock sound with Exile on Main St. (1972). Initially receiving mixed reviews, according to critic Steve Erlewine it is now "generally regarded as the Rolling Stones' finest album". They continued to pursue the riff-heavy sound on albums including It's Only Rock 'n' Roll (1974) and Black and Blue (1976). Led Zeppelin began to mix elements of world and folk music into their hard rock from Led Zeppelin III (1970) and Led Zeppelin IV (1971). The latter included the track "Stairway to Heaven", which would become the most played song in the history of album-oriented radio. Deep Purple continued to define hard rock, particularly with their album Machine Head (1972), which included the tracks "Highway Star" and "Smoke on the Water". In 1975 guitarist Ritchie Blackmore left, going on to form Rainbow and after the break-up of the band the next year, vocalist David Coverdale formed Whitesnake. 1970 saw The Who release Live at Leeds, often seen as the archetypal hard rock live album, and the following year they released their highly acclaimed album Who's Next, which mixed heavy rock with extensive use of synthesizers. Subsequent albums, including Quadrophenia (1973), built on this sound before Who Are You (1978), their last album before the death of pioneering rock drummer Keith Moon later that year.
Document 9: Take Me Home Tonight (song): By the mid-1980s, Eddie Money had reached a low - point in his recording career after several years of drug abuse. Columbia Records still wanted to keep Money on its roster, but restricted his creative control regarding his output. Record producer Richie Zito brought Money the song ``Take Me Home Tonight '', and Money would recall:`` I did n't care for the demo (but) it did have a good catch line. When I heard (a snippet of) 'Be My Baby' in it I said: 'Why ca n't we get Ronnie Spector to sing it?' (and was told) 'That's impossible.''' Money invited his friend Martha Davis, lead vocalist of the Motels, to sing the lines from ``Be My Baby ''on`` Take Me Home Tonight'': Davis encouraged him to try to recruit Spector herself and Money was eventually able to speak on the phone to Spector at her home in northern California: Money - ``I could hear clinking and clanking in the background... She said: 'I'm doing the dishes, and I got ta change the kids' bedding. I'm not really in the business anymore, Eddie. Phil Spector and all that, it was a nightmare '... I said' Ronnie, I got this song that's truly amazing and it's a tribute to you. It would be so great if you... did it with me. '''The success of`` Take Me Home Tonight'' encouraged Spector to resume her singing career. In 1987 Money would say of ``Take Me Home Tonight '':`` I did n't like the song, but... it helped Ronnie out and it helped me get some of my other material on the album across, so now I'm happy I did it.''
Document 10: Can't You Hear Me Knocking: ``Ca n't You Hear Me Knocking ''is a song by English rock band the Rolling Stones from their 1971 album Sticky Fingers. The song is over seven minutes long, and begins with a Keith Richards open - G tuned guitar intro. At two minutes and forty - three seconds, an instrumental break begins, with Rocky Dijon on congas; tenor saxophonist Bobby Keys performs an extended saxophone solo over the guitar work of Richards and Mick Taylor, punctuated by the organ work of Billy Preston. At 4: 40 Taylor takes over from Keith and carries the song to its finish with a lengthy guitar solo.
Document 11: Rock in a Hard Place: Rock in a Hard Place is the seventh studio album by American hard rock band Aerosmith, released on August 27, 1982 through Columbia Records. It was certified gold on November 10, 1989. It is the only Aerosmith album not to feature lead guitarist Joe Perry, following his departure from the band in 1979. Rhythm guitarist Brad Whitford also left during the recording in 1981. The band spent $1.5 million on the recording of this album, which saw them reunited with producer Jack Douglas. Although the official website for Aerosmith lists the release date for "Rock in a Hard Place" as August 1, 1982, the album was originally scheduled for release on August 20, 1982. It was then delayed one week until August 27, 1982.
Document 12: Take It So Hard: "Take It So Hard" is the first single from Keith Richards' first solo record, "Talk Is Cheap". The long-time Rolling Stones guitarist  recorded the record after band mate Mick Jagger refused to tour in 1986 in support of the album "Dirty Work". The second song of the eleven track record, it is a powerful example of vocal rock harmonies and rhythmic guitar, piano and percussion syncopation, with an overlay of vocal tracks that bury the lyrics within the push and pull of the music. It received heavy airplay on US rock radio, reaching #3 on Billboard's Mainstream Rock Tracks.
Document 13: Hard rock: Groups that emerged from the American psychedelic scene about the same time included Iron Butterfly, MC5, Blue Cheer and Vanilla Fudge. San Francisco band Blue Cheer released a crude and distorted cover of Eddie Cochran's classic "Summertime Blues", from their 1968 debut album Vincebus Eruptum, that outlined much of the later hard rock and heavy metal sound. The same month, Steppenwolf released its self-titled debut album, including "Born to Be Wild", which contained the first lyrical reference to heavy metal and helped popularise the style when it was used in the film Easy Rider (1969). Iron Butterfly's In-A-Gadda-Da-Vida (1968), with its 17-minute-long title track, using organs and with a lengthy drum solo, also prefigured later elements of the sound.
Document 14: Can't You Hear Me Knocking: "Can't You Hear Me Knocking" is a song by English rock band the Rolling Stones from their 1971 album "Sticky Fingers". The song is over seven minutes long, and begins with a Keith Richards open-G tuned guitar intro. At two minutes and forty-three seconds, an instrumental break begins, with Rocky Dijon on congas; tenor saxophonist Bobby Keys performs an extended saxophone solo over the guitar work of Richards and Mick Taylor, punctuated by the organ work of Billy Preston. At 4:40 Taylor takes over from Richards and carries the song to its finish with a lengthy guitar solo.
Document 15: Hard rock: 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."
