A Guy Called Gerald

Gerald Rydel Simpson (born 16 February 1967), better known as A Guy Called Gerald, is a British record producer and musician. He was an early member of the electronic group 808 State, contributing to their debut LP Newbuild (1988) and hit single "Pacific State" (1989). He also achieved solo success with his 1988 hit single "Voodoo Ray", considered the first British-made acid house track, which became a touchstone of Manchester's acid house scene and reached No. 12 in the UK charts.

He embraced breakbeat production in the 1990s, with his 1995 album Black Secret Technology becoming a "much-touted candidate for 'best jungle album ever.'" He also ran the London-based independent record label Juice Box Records from 1991 to 1998.
