Led Zeppelin were an English rock band formed in London in 1968. The group consisted of guitarist Jimmy Page, singer Robert Plant, bassist and keyboardist John Paul Jones, and drummer John Bonham. The band's heavy, guitar-driven sound, rooted in blues and psychedelia on their early albums, has earned them recognition as one of the progenitors of heavy metal, though their unique style drew from a wide variety of influences, including folk music.
After changing their name from the New Yardbirds, Led Zeppelin signed a deal with Atlantic Records that afforded them considerable artistic freedom. Although the group was initially unpopular with critics, they achieved significant commercial success with albums such as Led Zeppelin (1969), Led Zeppelin II (1969), Led Zeppelin III (1970), Led Zeppelin IV (1971), Houses of the Holy (1973), and Physical Graffiti (1975). Their fourth album, which features the track Stairway to Heaven, is among the most popular and influential works in rock music, and it helped to secure the group's popularity.
