Guns N' Roses (sometimes abbreviated as GN'R or GNR) is an American hard rock band. The band formed in Hollywood, Los Angeles, California in 1985. Led by frontman and co-founder Axl Rose  (born William Bruce Rose, Jr.), the band has released six studio albums, three EPs, and one live album while going through numerous line-up changes and controversies since its formation.

The band has sold more than 100 million albums worldwide, including 46 million in the United States. The band's 1987 major label debut album, Appetite for Destruction, has sold in excess of 28 million copies worldwide and reached No. 1 on the United States Billboard 200. In addition, the album charted three Top 10 hits on the Billboard Hot 100, including "Sweet Child o' Mine" which reached No. 1. The 1991 albums Use Your Illusion I and Use Your Illusion II debuted on the two highest spots on the Billboard 200 and have sold a combined 14 million copies in the United States alone and 35 million worldwide. After over a decade of work, the band released their follow-up album, Chinese Democracy.

The current lineup comprises lead vocalist Axl Rose, lead guitarists Ron "Bumblefoot" Thal and DJ Ashba, rhythm guitarist Richard Fortus, bassist Tommy Stinson, keyboardists Dizzy Reed and Chris Pitman and drummer Frank Ferrer.

Guns N' Roses' mid-to-late 1980s and early 1990s years have been described by individuals in the music industry as the period in which "they brought forth a hedonistic rebelliousness and revived the punk attitude-driven hard rock scene, reminiscent of the early Rolling Stones."

The group was formed in early 1985 by Hollywood Rose members Axl Rose (vocals) and Izzy Stradlin (rhythm guitar), and L.A. Guns members Tracii Guns (lead guitar), Ole Beich (bass) and Rob Gardner (drums).  The new band created its name by combining two of the group members' names. After only a short time (several reports indicate only 2 or 3 gigs were played with Guns, Beich & Gardner), bassist Ole Beich was fired and replaced by Duff McKagan while Tracii Guns lack of attendance at rehearsal led to the arrival of Slash.

Slash had played with McKagan in Road Crew and with Stradlin during a short stint in Hollywood Rose. The new line-up came together quickly, but after deciding to go on a "tour" from Sacramento, California, to Duff's home town of Seattle, Washington, drummer Rob Gardner quit and was replaced by Slash's close friend Steven Adler. The band, which continued to be called Guns N' Roses even after the departure of Tracii Guns, established its first stable line up on the so-called Hell Tour.

The music of Guns N' Roses is a fusion of punk rock, blues-rock, heavy metal and classic rock and roll. 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. While Reed has remained on some of the Chinese Democracy  demos, tours since 2000 have not included wind instruments, though the band has employed synthesized horns on some of their new songs.

A heavy influence on both the image and sound of the band was Finnish band Hanoi Rocks (singer Michael Monroe and Rose have collaborated on various occasions). Rose has stated that the band was massively inspired by groups like Queen, AC/DC, The Rolling Stones, and Rose Tattoo and that the sound of Appetite for Destruction was influenced by AC/DC, Led Zeppelin, Aerosmith, the New York Dolls and Hanoi Rocks.
