Close behind the Turtles in the catalog sequence comes BG-16 and another import from outside the San Francisco scene: the Mindbenders. The group had been Wayne Fontana & the Mindbenders when "The Game of Love" topped the American charts in 1965; after Fontana left for a solo career, the remaining Mindbenders scored again on their own with "A Groovy Kind of Love" in 1966. A British-Invasion pop act, in other words, dropped into Bill Graham's Fillmore in the middle of the summer the local bands were busy inventing something else entirely.

And again the local scene was right there underneath them: the support was the Chocolate Watchband, the San Jose garage-psych band whose fuzz-and-snarl sound was about as far from "A Groovy Kind of Love" as a single bill could stretch. The Fillmore's 1966 calendar was exactly this kind of place -- where the transatlantic pop mainstream and the nascent acid-rock underground brushed past each other -- and BG-16 is a clean document of that brush.

The poster is again Wes Wilson's, part of the unbroken run of early designs that taught San Francisco what a rock poster could look like. As with its neighbor BG-15, this page stops where the headless sourcing stopped: the exact date and run length are not asserted (the record is flagged approximate), and the Mindbenders-vs-Fontana billing is read as the post-Fontana touring group, the likeliest reading rather than a confirmed one. What is solid -- catalog position right after BG-15 and BG-14, the Mindbenders as headliner over the Chocolate Watchband, Wilson's art, the Fillmore under Graham in the summer of 1966 -- is the page. The rest is honestly left open rather than dishonestly filled.
