No Mercy was a thrash metal band from Venice, California, the brainchild of guitar player Mike Clark, who later played in Suicidal Tendencies. The band started in 1982 and featured lead vocalist Kevin Guercio, guitarist Mike Clark, bassist Ric "Rancid" Clayton (the artist who designed the Suicidal Tendencies logo as well as the shirts on S.T.'s first album) and drummer Sal Troy. Guercio recorded a few demos and the tracks on the Welcome To Venice (1985) compilation before being fired and replaced by Suicidal Tendencies lead vocalist Mike Muir. Read more on Last.fm
