I happen to have a double CD with complete recordings by Gattch...Mr Marquez seems to be looking for it so I uploaded the CD in 4 parts. First 2 links are for the album (contains some alternate takes) and the other 2 from a concert. The band were from Czechoslovakia (Slovak part)and the album was released in 1971. It is fairly good prog/jazz/rock music that people may enjoy. The front cover is included in the first .rar file.
Thank you, Marian!
