August, 1970 was busy for Bill Graham, and mid-month concerts ranging from blues to acid rock and including big-names and no-names had to be scheduled and promoted. Singer found the large triptych to be a useful vehicle, and arranged the performers around another classical-style collage. Scheduling and anticipated audience size caused Van Morrison's show to be held at the Berkeley Community Center and Led Zeppelin's to be held at the Oakland Coliseum.
This oversized poster was only printed once before the concert. It measures 21" x 27 15/16".
During his Fillmore era, from 1969-1971, Singer created more posters for Graham than any other artist. Singer's posters are notable for his use of collage, incorporating thousands of images clipped from magazines spanning several decades. He developed a format that included a stunning variety of lettering styles, applying them in close relation to the theme or subject of a poster.
