KIϟϟ is an American rock band formed in New York City in 1973 by Paul Stanley (vocals, rhythm guitar), Gene Simmons (vocals, bass), Ace Frehley (lead guitar, vocals), and Peter Criss (drums, vocals). Known for their face paint and stage outfits, the group rose to prominence in the mid-1970s with shock rock-style live performances which featured fire-breathing, blood-spitting, smoking guitars, shooting rockets, levitating drum kits, and pyrotechnics. The band has gone through several lineup changes, with Stanley and Simmons remaining the only consistent members. The current lineup consists of Stanley, Simmons, guitarist Tommy Thayer and drummer Eric Singer.

With their makeup and costumes, the band members took on the personae of comic book-style characters: the Starchild (Stanley), the Demon (Simmons), the Spaceman or Space Ace (Frehley), and the Catman (Criss). Due to creative differences, Criss departed the band in 1980 and Frehley in 1982, though both would return later.

Kiss has also earned 30 Gold albums, the most of any band from the United States. Kiss has 14 Platinum albums, three of which earned multi-Platinum.
