Rise with KISS
Formation and Breakthrough

In 1973, Gene Simmons co-created the rock band KISS in New York City, together with Paul Stanley, Ace Frehley and Peter Criss. The concept of the band combined hard rock music with theatrical performance: face paint, costumes, pyrotechnics and over the top performances.

They battled in the initial stages but through perseverance and live concerts they made it in the mid 1970s. They gained an identity by their 1975 anthem, Rock and Roll all nite.   Simmons has discussed the process by which the song was created when he was on a trip with Stanley, relating minor details to a major concept.

Simmons played bass as well as giving vocals.   The Demon (his stage character) entailed spitting blood, breathing fire, as well as protruding a long tongue during his performances.  Theatrical crusading turned into a part of the KISS name.
