Kiss was an American rock band formed in New York City in 1973 by Paul Stanley, Gene Simmons, Ace Frehley and Peter Criss. Known for their face paint and stage outfits, the group rose to prominence in the mid-1970s with shock rock–style live performances that featured fire-breathing, blood-spitting, smoking guitars, shooting rockets, levitating drum kits and pyrotechnics. The band went through several lineup changes, starting with drummer Eric Carr replacing original drummer Peter Criss in 1980, with Stanley and Simmons remaining the only consistent members. The final lineup consisted of Stanley, Simmons, Tommy Thayer and Eric Singer.
