He is best known as the lead guitarist of the American hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s and early 1990s.  During his later years with Guns N' Roses, Slash formed the side project Slash's Snakepit.  After leaving Guns N' Roses in 1996, he co-founded the supergroup Velvet Revolver, which re-established him as a mainstream performer in the mid to late 2000s.  Slash has since released three solo albums: "Slash" (2010), featuring an array of famous guest musicians, and "Apocalyptic Love" (2012) and "World on Fire" (2014), recorded with his band, Myles Kennedy and the Conspirators.  He returned to Guns N' Roses in 2016, nearly 20 years after he had left. "The Spaghetti Incident?"  is the fifth studio album by the American hard rock band Guns N' Roses.

Bolstered by the lead single "You Could Be Mine," "Use Your Illusion II" was the slightly more popular of the two albums, selling 770,000 copies its first week and debuting at No. 1 on the U.S. charts, ahead of "Use Your Illusion I"'s first week sales of 685,000.
