Guns N' Roses is an American hard rock band formed in Los Angeles, California, in 1985, as the result of a merger between local bands L.A. Guns and Hollywood Rose. When they signed to Geffen Records in 1986, the band's "classic" line-up consisted of vocalist Axl Rose, lead guitarist Slash, rhythm guitarist Izzy Stradlin, bassist Duff McKagan, and drummer Steven Adler. The current line-up consists of Rose, Slash, McKagan, guitarist Richard Fortus, drummer Isaac Carpenter, and keyboardists Dizzy Reed and Melissa Reese.

Guns N' Roses heavily toured the West Coast club circuit during their early years. Their debut album Appetite for Destruction (1987), supported by the eponymous tour, failed to gain traction, debuting at number 182 on the Billboard 200, until a year after its release when a grassroots campaign for the "Welcome to the Jungle" music video brought the band mainstream popularity.  "Welcome to the Jungle" and "Paradise City" both became top 10 singles, with "Sweet Child o' Mine" becoming the band's only single to reach number one on the Billboard Hot 100. The album has sold approximately 30 million copies worldwide, including 18 million units in the United States, making it the country's best-selling debut album and eleventh-best-selling album.
