Sporting the balance and complexity of a playing card on its left side, the right half of BG034 announces the psychedelic presence of punk-rock pioneer Captain Beefheart & His Magic Band.
The handbill was only printed once before the concert and measures 4 7/8" x 6 13/16".
When the Avalon Ballroom and Bill Graham's Fillmore Auditorium began to hold weekly dance concerts, Wilson was called upon to design the posters. He created psychedelic posters from February 1966 to May 1967, when disputes over money severed his connection with Graham. Wilson pioneered the psychedelic rock poster. Intended for a particular audience, "one that was tuned in to the psychedelic experience," his art, and especially the exaggerated freehand lettering, emerged from Wilson's own involvement with that experience and the psychedelic art of light shows.
