Funny. Wavves doesn't show up on the soundtrack for the soon-to-be-released Scott Pilgrim vs. the World, but it sounds like his "Post Acid" might be featured in this four-minute animated short based on Bryan lee O'Malley's award-winning comic book series. Via Slashfilm:
"Scott Pilgrim vs the Animation airs Thursday August 12th in two parts between 12 and 12:30 am, inside commercial breaks on [adult swim]. It will also be available in full on adultswim.com, and on the [adult swim] and Scott Pilgrim Facebook pages the day after it airs."
