In my search to find other vocoder bands this evening, I came across SpaceSynth.net.
SpaceSynth is 80s-sounding synth music with a peppy upbeat flavor. It sounds like a lot of what I heard in PC and Amiga demos when I was a kid. Interestingly enough, SpaceSynth is nowhere to be found in Ishkur’s famous guide.
Go download Through The Space by Galaxion and you’ll get a pretty good feel for the genre.
And yes, a few SS artists use vocoders. Bless them! Even if science finally figures out how to make robots sing someday, vocoders will still sound better. Or at least cooler, anyway.
