In September 1991, Guns N' Roses released the albums "Use Your Illusion I" and "Use Your Illusion II", which sold a combined 11 million copies in the United States. In November 1991, during the Use Your Illusion Tour, rhythm guitarist and founding member Izzy Stradlin abruptly left the band, citing touring exhaustion and conflicts with his bandmates. He was replaced by Gilby Clarke. In November 1993, Guns N' Roses released ""The Spaghetti Incident?"", an album of covers of mostly glam rock and punk rock songs. Though it was certified platinum in 1994, it sold significantly less than their previous releases.
