In 1998 to be more specific Matmos was going things that a lot of people are trying to do today. Take this sound sample from Verber: Synapse, track 9 from what looks like their first Release. It sure as hell sounds a lot like an opto theremin or some sort of a DIY oscillator, possibly even with a ring mod effect. No delay or anything and its mixed pretty dry and up front. I do enjoy their dynamics despite the constant repetition. Not just noise, but something that is constructive and has a point. Matmos’ discography can be found here along with more info on the band.
