Jimi Hendrix mixing at The Record Plant, NYC 1968.
"Jimi was totally into the technology of the day as demonstrated by his ability at the board. We often mixed together as a team mostly ending in very creative collaborations or falling over laughing at the mess we had made of the sound. In fact "1983 (A Merman I should turn to be) " was mixed as one complete take with two or three rehearsals before hand."
