There are more than two bands under the name Rigor Mortis: 1- Originally formed in 1983 when schoolmates Harden Harrison and Casey Orr met Mike Scaccia. The three shared a love for horror/gore flicks and extremely heavy music, and that recipe helped them create a truly unique form of speed metal that had never been heard before. Within five years they had virtually created the thrash metal scene in Texas. In 1988, with Bruce Corbitt on vocals, Rigor Mortis released their self-titled debut album on Capitol Records
