Led Zeppelin were an English rock band formed in London in 1968. The group consisted of guitarist Jimmy Page, singer Robert Plant, bassist/keyboardist John Paul Jones, and drummer John Bonham. Along with Black Sabbath and Deep Purple, the band's heavy, guitar-driven sound has led them to be cited as one of the progenitors of heavy metal. Their style drew from a wide variety of influences, including blues, psychedelia, and 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 were initially unpopular with critics, they achieved significant commercial success with eight studio albums released over eleven years, from Led Zeppelin (1969) to In Through the Out Door (1979). Their untitled fourth studio album, commonly known as Led Zeppelin IV (1971) and featuring the song "Stairway to Heaven", is among the most popular and influential works in rock music, and it helped to secure the group's popularity.
Page wrote most of Led Zeppelin's music, particularly early in their career, while Plant generally supplied the lyrics. Jones' keyboard-based compositions later became central to the group's catalogue, which featured increasing experimentation. The latter half of their career saw a series of record-breaking tours that earned the group a reputation for excess and debauchery. Although they remained commercially and critically successful, their output and touring schedule were limited during the late 1970s, and the group disbanded following Bonham's death from alcohol-related asphyxia in 1980. In the decades that followed, the surviving members sporadically collaborated and participated in one-off Led Zeppelin reunions. The most successful of these was the 2007 Ahmet Ertegun Tribute Concert in London, with Jason Bonham taking his late father's place behind the drums.
Many critics consider Led Zeppelin to be one of the most successful, innovative, and influential rock groups in history. They are one of the best-selling music artists in the history of audio recording; various sources estimate the group's record sales at 200 to 300 million units worldwide. With RIAA-certified sales of 111.5 million units, they are the third-best-selling band in the US. Each of their nine studio albums placed in the top 10 of the Billboard album chart and six reached the number-one spot. They achieved eight consecutive UK number-one albums. Rolling Stone magazine described them as "the heaviest band of all time", "the biggest band of the Seventies", and "unquestionably one of the most enduring bands in rock history". They were inducted into the Rock and Roll Hall of Fame in 1995; the museum's biography of the band states that they were "as influential" during the 1970s as the Beatles were during the 1960s.
