Bill Graham invented "The Sound" to call to mind the home-brew, local San Francisco bands that he featured at his venues. In BG029, Wes Wilson captured the curvaceous female form in one of the best examples of his work.
All handbills were printed prior to the concert.
The original handbill (see BG029-1A) is black and white like the 1st printing of the poster. It measures 5 1/16" x 8 5/8".
The 1st printing B handbill matches the poster of the same name, displaying a magenta/lavender outlined figure. Some copies have a printing flaw where the background green infringes on the lower legs of the figure. This handbill measures 4 15/16" x 8 13/16".
1st printing C (see BG029-1C) matches its respective poster with a blue/violet outlined female figure. It measures 4 15/16" x 8 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.
