Johnny "Guitar" Watson was an innovative and trend-setting guitarist. He experimented with feedback and other techniques long before the guitar heroes of progressive rock began playing with electrically amplified sounds in a similar manner. He released his early masterpiece showcasing these sounds in 1954 with the scintillating instrumental "Space Guitar". He had a profound influence on many avant-garde guitarists, among them the "Freak Daddy" Frank Zappa, who later invited Watson to work on his brilliant hit album "One Size Fits All" in 1975. This episode of Ohne Filter was filmed on July 02, 1990.
