Singer's poster was reminiscent of BG216, although slightly less psychedelic in reference. The concert featured Lee Michaels, touted as a funky, white-boy soul singer, and blues-great Albert King.
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.
