Classical drawings and cool cats at rest were Singer's choices for those giants among Blues players, B.B. King and Albert King, who played together for four nights at the Fillmore West.
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.
