Deep Purple

Deep Purple are an English rock band formed in Hertford in 1968. Along with Led Zeppelin and Black Sabbath, they are considered to be among the pioneers of heavy metal and modern hard rock, although some band members believe that their music cannot be categorised as belonging to any one genre. They were once listed by the Guinness Book of World Records as "the loudest pop group", and have sold over 100 million albums worldwide. Deep Purple were ranked #22 on VH1's Greatest Artists of Hard Rock programme.

Queen

Queen are a British rock band formed in London in 1971, originally consisting of Freddie Mercury (lead vocals, piano), Brian May (guitar, vocals), John Deacon (bass guitar), and Roger Taylor (drums, vocals). Queen's earliest works were heavily influenced by progressive rock; in the mid-1970s, the band ventured into more conventional and radio-friendly works, bringing them greater commercial success. It also became something of a trademark to incorporate more diverse and innovative styles in their music, exploring the likes of vaudeville, gospel music, electronic music and funk.

Led Zeppelin

Led Zeppelin were an English rock band formed in 1968 that consisted of guitarist Jimmy Page, singer Robert Plant, drummer John Bonham, and bassist John Paul Jones. With their heavy, guitar-driven blues-rock sound, Led Zeppelin are regularly cited as one of the progenitors of heavy metaland hard rock, even though the band's individualistic style drew from many sources and transcends any one music genre. Led Zeppelin did not release songs from their albums as singles in the United Kingdom, as they preferred to develop the concept of album-oriented rock.

The Beatles

 The Beatles were an English rock band, formed in Liverpool in 1960. They are one of the most commercially successful and critically acclaimed acts in the history of popular music. From 1962, the group consisted of John Lennon (rhythm guitar, vocals), Paul McCartney (bass guitar, vocals), George Harrison (lead guitar, vocals) and Ringo Starr (drums, vocals). Rooted in skiffle and 1950s rock and roll, the group later worked in many genres ranging from pop ballads to psychedelic rock, often incorporating classical and other elements in innovative ways. The nature of their enormous popularity, which first emerged as "Beatlemania", transformed as their songwriting grew in sophistication. They came to be perceived as the embodiment of ideals of the social and cultural revolutions of the 1960s.

The Rolling Stones

The Rolling Stones are an English rock band, formed in London in April 1962 by guitarist and harmonica player Brian Jones and pianist Ian Stewart, with vocalist and harmonica player Mick Jagger and guitarist Keith Richards. Bassist Bill Wyman and drummer Charlie Watts completed the early lineup. The Rolling Stones raised the international regard for the primitive blues typified by Chess Records' artists such as Muddy Waters, who wrote the song after which the band is named, Rollin' Stone. American R&B and blues cover songs dominated the Rolling Stones' early material, but their repertoire has always included rock and roll. The Rolling Stones have endured and stayed relevant, said critic and musicologist Robert Palmer, by remaining "rooted in traditional verities, in rhythm-and-blues and soul music", while "more ephemeral pop fashions have come and gone".
