Rob Tyner (December 12, 1944 – September 17, 1991) was an American musician best known as lead singer for the proto-punk rock band MC5. Born Robert Derminer, his adopted surname was in tribute to the jazz pianist McCoy Tyner. It was Tyner who issued the infamous rallying cry of "kick out the jams, motherfuckers" at the MC5's live concerts. Tyner had originally auditioned as the bass player, but the band felt his talents would be best used as a lead vocalist.
