This is what I believe to be the band's entire discography. If there were other releases, please let me know. Both records self-released in the US on Prehistoric Records, and feature 2 minimal synth gems a piece.
Infatuation was produced by Ian North, who made a great 12" EP called "Rape Of Orchids", which I will post... hmm, after this!
