Singer abandoned the neat, picture-frame borders of his early posters for BG285. Here, swirling red smoke wound into joyful, bird-like figures to announce Boz Scaggs headlining at one of the last Fillmore West concerts.
During his Fillmore era, from 1969-1971, Singer created more posters for Graham than any other artist.

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.
