Singer's collages rarely related to the bands or events they advertised. BG227 was a study of forms: the parallel chambers of the nautilus released, or perhaps contained, the stuff of galaxies, and the brightly-defined triangle represented the spiritual. The pure beauty of the design made BG227 a piece of original art. The concert was another example of Bill Graham serving the fans both what they wanted and what they needed: The Grateful Dead and Miles Davis.
The handbill was only printed once before the concert and presents a calendar of upcoming Bill Graham events on the reverse. It measures 4 5/8" x 7".
There were also some pre-concert postcard mailers printed that were conjoined with the BG228 image (see BG227/228). They measure 7" x 9 1/4".
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.
