Led Zeppelin was an English rock band, active in the late 1960s and throughout the 1970s. Formed in 1968, it consisted of guitarist Jimmy Page, singer Robert Plant, bassist/keyboardist John Paul Jones, and drummer John Bonham.With its heavy, guitar-driven blues rock sound, Led Zeppelin is regularly cited as one of the progenitors of heavy metal and hard rock even though the band's individualistic style drew from many sources and transcends any single music genre. The band is widely considered to be one of the most successful, innovative and influential groups in the history of music.
