Amun Ra "Magic Circle" unreleased Krautrock acetate

This is one of three tracks of this acetate, which belongs to a friend of mine. We do not know anything about the band, when exactly it was recorded and how many of these acetates are existing. We would be glad to get some information. If you know anything, please contact me. It was recorded in the Meilhaus Studio in Munich, like Yggdrasil, which became a CD release on Garden of Delights in 2009. So probably the band also was from Munich, maybe around the same time? Enjoy listening, it's really nice!
