Being released privately by the group and Josef Alterbaum (who recorded and mixed it) and pressed in limited quantities makes it almost impossible to find on original vinyl. The wonderful person I got my copy from bought it directly from the group when they were touring Germany in 1978.
The music is somewhere between Krautrock and proper Jazzrock (with Jazzrock being the stronger part in the mix)) and I guess it will appeal to Jazzheads as to Kraut-Fans. Partially very funky and then there's that Ethno vibe in some of the tracks that we love a lot. Supposingly Gert Lueken is responsible for these vibes. He wrote, arranged and played synths, piano, percussion and clarinet on Tri Atma records some years later! In 1975 he played live with the Krautjazzers Thirsty Moon (highly recommended too and a lot easier to find... reissues!!!)
Over at Green Brain and Friends they say that the guys were also responsible for the Malcom Locks LP but I couldn't find any more information on that, so I dare to call it a rumour. If you know more, please TELL US! Cheers!
