Guns N' Roses are an American hard rock band that gained fame during the late 1980s and early 1990s. The band's 1987 major label debut, APPETITE FOR DESTRUCTION, earned them worldwide popularity; their 1991 effort, the simultaneous releases of USE YOUR ILLUSION I and USE YOUR ILLUSION II, and the subsequent tour solidified those gains. Guns N' Roses have sold an estimated 90 million albums worldwide. Guns N' Roses helped usher in a new era in the hard rock genre. While glam metal dominated the airwaves in the late 1980s, the band's style of music, onstage presence, and image created a new movement within the then dominant rock and metal scene, as they offered a grittier, more traditionalist take on rock music and won many fans who admired their apparent authenticity. The band achieved worldwide success during the period of 1987-1993, but the clashing personalities of various band members, coupled with heavy alcohol and drug abuse and the erratic behavior of frontman Axl Rose hindered the group's ability to work together. Today, Rose is the only original member in the band's current lineup. The band was founded in Los Angeles in March, 1985. Their unique style integrated hard rock, blues and other genres of music into the popular heavy metal music of the time. The band was formed by singer Axl Rose, guitarists Tracii Guns and Izzy Stradlin, bassist Ole Beich (later replaced by Duff McKagan), and drummer Rob Gardner. The name was derived from two bands in which the original members had played: Hollywood Rose and L.A. Guns.
