The Swiss thrash metal band Coroner was formed in 1985 and had the same line-up throughout the whole band history. Without a singer of their own the Celtic Frost vocalist Tom G. Warrior helped them out on their first demo called "Death Cult Lodge". Soon they were also signed to the same label as Celtic Frost namely Noise Records. In 1987 their debut album "R.I.P." was released, followed by a shorter European tour. After the break-up in 1994 Tommy formed his own band Clockwork.
