Quicksilver Messenger Service Handbill
The Independence Ball was three days of great music that included appearances by three of the top four San Francisco bands: The Grateful Dead, Quicksilver Messenger Service and Big Brother & the Holding Co. Not long after this concert, Grace Slick would leave the Great Society to join the Airplane.
The handbill was only printed once before the concert in green ink on thin white paper. Union logo 221 is in the lower right corner, and it measures 5 7/16" x 8 1/2".
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.
