Klaus Schulze--Stars are Burning. Speaking of official boots, here's a two disc set released by the artist via his manager/publisher, Klaus D. Mueller. Audience recordings from 1977 and 1979 that circulated for years, now cleaned up and official. The coughing guy is here, he even blows his nose as an added bonus. Not high fidelity but a cool memento of the time period. Recommended only for those with more than a casual interest in KS. As on the La Vie Electronique sets, Mueller gives some really idiotic titles to some of the tracks.
I see there's now another TD bootleg box on Esoteric, I think from around 78-80.
