Although the sound's roots can be traced back to 1985, it was in 1987 that techno really began to emerge, fully formed, from the Motor City of Detroit. One of the first examples of the sound could be found on the flipside of Model 500's Sound of Stereo EP. It was called "Off To Battle", and expertly fixed alien synthesizers, wonky acid lines and hushed vocal samples to a blistering rhythm track. It remains one of the finest cuts in the Detroit canon, as this essential reissue proves. Echoes of early techno's obsession with fizzing drum builds and bold string samples can also be heard on "Electric Entourage", while "Sound of Stereo" - available in remixed and instrumental flavours - still sounds like a futurist's take on Chicago house.
