Detroit flop city? KISS singer and bassist Gene Simmons took a spill this weekend during a concert in Montana.

Simmons and the group were performing the hit KISS song “Rock and Roll All Nite” in Bozeman, Montana, when the fall occurred. The 66-year-old started walking backwards on the stage, and hit a raised platform behind him. He fell straight onto his back, and was helped to his feet by a stage hand.

Nothing stops rock, however: Simmons continued on with the show like nothing had happened. Check out the video below.
