full_context: Document 1: 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 2: Help Me Girl: "Help Me Girl" is a song performed by Eric Burdon in 1966. It was billed to Eric Burdon for his 1967 solo album, "Eric Is Here" which also featured drummer Barry Jenkins, the only group member to remain during the transition from the "first" Animals group to the "new" lineup. It reached number 29 on the U.S. charts and number 14 on the UK charts.

Document 4: The House of the Rising Sun: ``The House of the Rising Sun ''is a traditional folk song, sometimes called`` Rising Sun Blues''. It tells of a life gone wrong in New Orleans; many versions also urge a sibling to avoid the same fate. The most successful commercial version, recorded in 1964 by British rock group the Animals, was a number one hit on the UK Singles Chart and also in the United States and France. As a traditional folk song recorded by an electric rock band, it has been described as the ``first folk - rock hit ''.
Document 5: London: London's bus network is one of the largest in the world, running 24 hours a day, with about 8,500 buses, more than 700 bus routes and around 19,500 bus stops. In 2013, the network had more than 2 billion commuter trips per annum, more than the Underground. Around £850 million is taken in revenue each year. London has the largest wheelchair accessible network in the world and, from the 3rd quarter of 2007, became more accessible to hearing and visually impaired passengers as audio-visual announcements were introduced. The distinctive red double-decker buses are an internationally recognised trademark of London transport along with black cabs and the Tube.
Document 6: Telegram messenger: By the 1960s the number of telegrams being delivered had dropped to 10 million, and in 1976 only 844 were delivered. Consequently the Post Office took the decision in 1977 to abolish the service. The service continued for a few years and was briefly operated by British Telecom after it split from the Post Office. British Telecom announced on 19 October 1981 that the telegram would be discontinued, and it was finally taken out of service on 30 September 1982 after 139 years in the United Kingdom.
Document 7: Mr. Tambourine Man: The song has been performed and recorded by many artists, including the Byrds, Judy Collins, Melanie, Odetta, and Stevie Wonder among others. The Byrds version was released in April of 1965 as their first single on Columbia Records, reaching number 1 on both the "Billboard" Hot 100 chart and the UK Singles Chart, as well as being the title track of their debut album, "Mr. Tambourine Man." The Byrds' recording of the song was influential in popularizing the musical subgenres of folk rock and jangle pop, leading many contemporary bands to mimic its fusion of jangly guitars and intellectual lyrics in the wake of the single's success.
Document 8: 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 9: The Animals discography: The discography of The Animals, an English music group of the 1960s formed in Newcastle upon Tyne, contains 20 studio albums, 6 compilation albums, 5 EPs and 25 singles. Featuring a gritty, bluesy sound and a deep-voiced frontman in Eric Burdon, they are best known for their rendition of an American folk song named "House of the Rising Sun", which is described by many as their signature song. This single had worldwide sales of nearly 5 million and became a Number One hit in both the UK and US in 1964. Overall, the group balanced tough, rock-edged pop singles such as "We Gotta Get Out of This Place" and "It's My Life" against rhythm and blues-oriented album material. The Animals released separate UK and US albums, a practice common to other British Invasion bands of the time such as The Beatles and The Rolling Stones.
Document 10: 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 12: Southampton: There are two main termini for bus services. As the biggest operator, First uses stops around Pound Tree Road. This leaves the other terminal of West Quay available for other operators. Uni-link passes West Quay in both directions, and Wilts & Dorset drop passengers off and pick them up there, terminating at a series of bus stands along the road. Certain Bluestar services also do this, while others stop at Bargate and some loop round West Quay, stopping at Hanover Buildings. There was a tram system from 1879 to 1949.
Document 13: New Haven, Connecticut: The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.

Document 15: Melbourne: Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 2013–2014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops. Around 80 per cent of Melbourne's tram network shares road space with other vehicles, while the rest of the network is separated or are light rail routes. Melbourne's trams are recognised as iconic cultural assets and a tourist attraction. Heritage trams operate on the free City Circle route, intended for visitors to Melbourne, and heritage restaurant trams travel through the city and surrounding areas during the evening. Melbourne is currently building 50 new E Class trams with some already in service in 2014. The E Class trams are about 30 metres long and are superior to the C2 class tram of similar length. Melbourne's bus network consists of almost 300 routes which mainly service the outer suburbs and fill the gaps in the network between rail and tram services. 127.6 million passenger trips were recorded on Melbourne's buses in 2013–2014, an increase of 10.2 percent on the previous year.
