I bought the Faust Tapes when it was released because it was 49p.
I played it once and wondered if it was so cheap because some one had recorded them tuning up and there might be some songs on the next one?
They even managed to put their own name in the Bridget Riley print they used as a cover although you had to hold it an oblique angle and squint to see it. Or maybe you just had to be stoned, I can’t remember!
Anyway I still have my copy It has been over 40 years since I played it last
