According to the wikipedia...

Guns N' Roses is an American hard rock band, formed in Los Angeles, California in 1985. The band has sold an estimated 90 million albums worldwide, including 39 million in the United States.Their 1987 major label debut, Appetite for Destruction, sold over 26 million copies worldwide and reached #1 in the United States.

The band's musical style, onstage presence and bad boy rock image helped usher in a new era of the dominant hard rock and heavy metal scene of the late 1980s and early 1990s. While glam metal was the leading genre in record sales, video charts and radio airplay, Guns N' Roses offered a grittier, more traditional take on rock music, and won many fans who admired their apparent authenticity.

The band enjoyed worldwide success from 1988 to 1993, but clashing personalities of different band members led to the end of the core lineup. Today, frontman Axl Rose is the only original member left in the current Guns N' Roses line-up, having served as lead singer for twenty-two years since 1985.
