Here are the other two releases I have from Dier's Stichting Update Materials label. From P. Kok I already posted a 7" before. I believe he was the guitarist in Dier. He plays guitar, piano, synthesizer and such like and is somewhat industrial at times, sometimes a bit more musique concrete. (Bob) Wallagh plays rhythmbox, bass, guitar, synth, vocals and steel percussion. His cassette is only very short, but nice minimal synth music.
