Album: Various artists, Terry Farley Presents Acid Rain: Acid & Deep House 1985-1991 (Harmless)

Acid house is an endlessly compiled genre, but this five-disc collection may be the closest thing to a definitive take.

Twenty-five years since the scene's peak year of 1988, Farley concentrates on the sound's Chicago roots, with classics by the likes of Phuture, Bam Bam and DJ Pierre, almost all on original 12-inch club mixes. Obsessives will head straight for the previously unreleased "Bad Boy" by Frankie Knuckles, but the entirety amounts to an all-night Shoom set in itself.
