Completely agree that Richie Hawtin, Hardfloor and the likes of McBride on Drop Bass Network were the original acid techno - before any of the liberator crew were. If you look at old Ant and Geezer stuff on VCF and Dave the Drummer's Assault EP on Boscaland - its very, most definately acid trance. Routemaster/Cluster/SUF changed the sound to be more techno but definately wasn't the first acid techno even if they are strong innovators within the scene.
