In early 1990, Guns N' Roses returned to the studio to begin recording the full-length follow-up to "Appetite for Destruction". Recording sessions initially proved unproductive due to Steven Adler's struggle with drug addiction, which made him unable to perform and caused sessions to abort for several days at a time. Adler was fired the following July and replaced by Matt Sorum of The Cult. Keyboardist Dizzy Reed also joined the band that year at Rose's insistence. Sorum and Reed played their first show with Guns N' Roses at Rock in Rio 2 in January 1991. The group fired its long-time manager, Alan Niven, in May of that year; Rose reportedly forced the dismissal of Niven against the wishes of his bandmates by refusing to complete the new album until Niven was gone. He was replaced by roadie Doug Goldstein, whom Izzy Stradlin described as "the guy who gets to go over to Axl's at six in the morning after he's smashed his $60,000 grand piano out of the picture window".
