With Rocker Alter Ego have a plowdriver track that could easily march alongside T. Raumschmiere's Monster Truck Driver.
The electronic cowbell part is just as effective as its handheld counterpart was in the 70s Grand Funk track We're An American Band.
Taken from the album Transphormer, Rocker sounds perfect as a single, and has a really fine Acid House style mix by Black Strobe on the B-side.
Alter Ego are Roman Flügel and Jörn Elling from Germany. Besides dozens or releases as Alter Ego, they have recorded together under many names including Acid Jesus and Sensorama.
While I bought this 12inch for the Black Strobe B-side, I came to like the original version even better, and would love to hear the full length it was taken from.
