After playing a short European tour in the summer of 1980, the band began preparing for a longer North American tour when John Bonham suddenly died due to overconsumption of alcohol.  The band subsequently broke up, as Plant, Page, and Jones each pursued solo careers to varying degrees of success.  The three surviving members would reunite in 1985 for the [[Live Aid]] concert, in 1988 for the Atlantic Records 40th Anniversary concert, and in 1995 for their induction into the Rock and Roll Hall of Fame.  Page and Plant also reunited (without Jones) to record an album covering Led Zeppelin songs, and an album of originals.
