This is a very odd thing. I first heard it on a tape, issued by Stanley Schtinter. I spoke to him about it, how odd and interesting I thought it was. I then started investigating the weird, wild cinematic/art world of Franz Zwartjes. Have a look around yourself. Google him. YouTube him.
This album is “Tapes 1”. It is music form his archived tapes, of his noises and film music and sound recordings. “Tapes 2” is on the way.
