1990–1993: international success with Use Your Illusion
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 be delayed 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".
In May 1991, still without an album to promote, the band embarked on the two-and-a-half-year Use Your Illusion Tour, which became known for its financial success and myriad controversial incidents that occurred during shows, including late starts, on-stage rantings and even riots. Rose received much criticism for his late appearances at concerts, sometimes taking the stage hours after the band was scheduled to perform. In July 1991, 90 minutes into a concert at the Riverport Amphitheater near St. Louis, after on-stage requests from Rose for security personnel to confiscate a fan's video camera, Rose himself dived into the crowd to seize it. After being pulled back on stage, he announced, "Well, thanks to the lame-ass security, I'm going home!" and departed, following which some 2,500 fans staged a riot, resulting in an estimated $200,000 in damages.
In September 1991, with enough material completed for two albums, Guns N' Roses released Use Your Illusion I and Use Your Illusion II, which debuted at No. 2 and No. 1 respectively on the Billboard 200, a feat not achieved by any other group. By the albums' release, however, Rose's relationships with his bandmates had become increasingly strained. His childhood friend Izzy Stradlin abruptly left the group in November 1991; he was replaced by Gilby Clarke of Kill For Thrills. Of his reasons for leaving, Stradlin said, "I didn't like the complications that became such a part of daily life in Guns N' Roses," citing the riot and Rose's chronic lateness as examples, as well as his new-found sobriety making it difficult to be around other bandmates' continued alcohol and substance abuse.
On April 20, 1992, Rose performed with Elton John at The Freddie Mercury Tribute Concert at Wembley Stadium singing "Bohemian Rhapsody" as a duet with John and also sang "We Will Rock You".
Another riot occurred in August 1992 at Montreal's Olympic Stadium, during a co-headlining tour with Metallica. Prior to Guns N' Roses' appearance, Metallica's set was cut short after singer-guitarist James Hetfield suffered second-degree burns in a pyrotechnics accident. However, the shortened time between sets did not allow for adequate tuning of stage monitors, and the band members could not hear themselves. In addition, Rose claimed that his throat hurt, causing the band to collectively leave the stage early. The riot resulted in an estimated $400,000 in damages. In November of that year, Rose was convicted of property damage and assault in relation to the Riverport riot; he was fined $50,000 and received two years' probation.
Guns N' Roses played its final show of the Use Your Illusion Tour on July 17, 1993, at River Plate Stadium in Buenos Aires; it proved to be Rose's last live performance with the band for seven and a half years. The following August, Rose testified in court against Steven Adler, who had filed a lawsuit contending that he had been illegitimately fired. When the judge ruled against Rose, he agreed to an out-of-court settlement of $2,500,000 and 15% of the royalties for everything Adler recorded prior to his departure. In November of that year, Guns N' Roses released "The Spaghetti Incident?", a cover album of mostly punk songs, which proved less successful than its predecessors. Rose had included the hidden track "Look at Your Game, Girl", a song written by convicted murderer Charles Manson, which he intended as a personal message to his ex-girlfriend Stephanie Seymour. Controversy ensued, and the band subsequently pledged to donate any royalties to the son of one of Manson's victims.
