techno comes from detroit. it had antecedents, like kraftwerk, giorgio moroder, etc. these guys were influenced by electro-acoustic composers like steve reich, who was doing stuff that formed the bases of much of the conceptual ideas in techno back in the 1950s. gamelan has rhythmic and melodic patterns that heavily influenced steve reich. blah blah blah all the way back to the first caveman to bang a bone on a rock in roughly metered time.
