Founded by Thomas P. Heckmann in September 1994 and based in Mainz, Acid Fuckers Unite (A.F.U.) was a sublabel of Trope Recordings. Specializing in Acid Techno ...with House elements, the label acted as a vehicle for Heckmann's successful "Silent Breed" project, but also released records by Ian Pooley as "Ides" and Patrik Sjeren as "P.S.". The first fourteen singles were half pressed on black and coloured vinyl, but later on black vinyl only. Acid Fuckers Unite (A.F.U.) was distributed by Neuton. The label was discontinued along with its parent label Trope Recordings in 1998.
In March 2005 Acid Fuckers Unite (A.F.U.) was re-launched as "A.F.U. Limited", and is now distributed by Vinyl Labor after Discomania and Neuton's unfortunate endings. A.F.U. Limited continues to release Heckmann's cooler material in the new millenium.
