Guns N' Roses burst onto the Sunset Strip scene back in 1985 with a take-no-prisoners sound that was dirty and sleazy enough to frighten parents and teachers—a timely mix of glam irony, punk-rock slam, bluesy swagger, and metal crunch. You can trace their roof-raising sonics and attitude by way of The New York Dolls, The Rolling Stones, Judas Priest, and other rock 'n' roll insurgents.
