Meanwhile, Guns N' Roses' classic-lineup was whittled away throughout the decade. Drummer Steven Adler was fired in 1990, guitarist Izzy Stradlin left in late 1991 after recording "Use Your Illusion I and II" with the band. Tensions between the other band members and lead singer Axl Rose continued after the release of the 1993 punk rock covers album ""The Spaghetti Incident?"". Guitarist Slash left in 1996, followed by bassist Duff McKagan in 1998. Axl Rose, the only remaining member from the classic lineup at that point, worked with several lineups of the band to record "Chinese Democracy" – an album that would take over ten years to complete and see the band incorporate electronic rock, industrial rock and nu metal styles.
