Side one of a rare cassette recording of Electric Music by Pete Challis from a performance at the Nigel Greenwood Gallery 5/7/78 – 22/7/78. When the gallery went bankrupt in the 1990s boxes of stuff from the gallery were auctioned off at Sotheby’s. I bought a tea-chest of mixed items; artists’ books, LPs by Yves Klein “Prince of Space” and a few cassettes including the Pete Challis.
