Guns N' Roses is an American hard rock band from Los Angeles formed in 1985. The classic lineup, as signed to Geffen Records in 1986, consisted of vocalist Axl Rose, lead guitarist Slash, rhythm guitarist Izzy Stradlin, bassist Duff McKagan, and drummer Steven Adler. The current lineup consists of Rose, Slash, McKagan, keyboardists Dizzy Reed and Melissa Reese, guitarist Richard Fortus and drummer Frank Ferrer.
The band has released six studio albums, accumulating sales of more than 100 million records worldwide, including shipments of 45 million in the United States, making Guns N' Roses one of the world's best-selling bands of all time. They have been credited with reviving the mainstream popularity of rock music, at a time when popular music was dominated by dance music and glam metal. Its late 1980s and early 1990s years have been described as the period in which the group brought forth a "hedonistic rebelliousness" reminiscent of the early Rolling Stones, a reputation that had earned the group the nickname "the most dangerous band in the world". The band's classic lineup, along with later members Reed and drummer Matt Sorum, was inducted into the Rock and Roll Hall of Fame in 2012, in its first year of eligibility.
The music of Guns N' Roses is a fusion of punk rock, blues rock, heavy metal, hard rock, and hair metal. The Illusions albums saw the band branching out into art rock, while "The Spaghetti Incident?" saw the group blend hard rock with punk rock. Since the group's 1999 revival, the band has retained hard rock features while also experimenting with Industrial rock and electronic rock. In the 1990s, the band integrated keyed instruments (played by either Rose or Reed, and accompanied on tour by Teddy Andreadis) into the band, and for roughly half of the Use Your Illusion tour, added a horn section to the stage.
