German pharmacist, family woman and explorer of the esoteric, Ursula Bogner, left behind a vast collection of electronic music she made in her home studio from the 1960s until her death in 1994. Electronic musician Jan Jelinek has compiled and preserved her lighthearted and quirky work and made it available to the public.
I found it to be a lot of fun and you can enjoy samples of it on Jelinek's Faitiche website. It reminded me a little of The Residents, but it has its own unique feel. After listening to the tracks, try playing them at the same time for a very interesting effect.
