Super Disc Inc.

Founded in Detroit in 1974 by former HDH Sound Studios engineers Bob Dennis and Greg Reilly.
Commonly referred to as Superdisc, the studio would operate under this name until 1983 when Dennis and Reilly split their business into two different companies and Superdisc became The Disc Ltd., run by Reilly.

Originally housed in HDH Studios old building, Superdisc would buy out Pro Sound Studios in East Detroit in 1976 and move in to its facility.
Superdisc was at the time one of the largest studios in Detroit and collaborated frequently with George Clinton and related acts.
