Despite its short existence, Demon Thor was one of the most sensational, continental rock groups in the 70's. It was the very first German band performing on the legendary TV-Show 'Musikladen', the very first performance act in the ‘Circus Kronebau’ in the city of Munich, Germany; the band won music awards in France and England, and both of their albums were published world wide by United Artists. The band was a Swiss rock-scene fusion between Tommy Fortmann and Krokodil, as well as singer Geff Harrison (Twenty Sixty Six And Then), Peter Bischof, and Oliver Freytag. The two full-length albums were re-released on CD (using its original covers) by Spalax France.
