This fall, Dr. Dog teamed up with Pig Iron Theater Company to produce Swamp (IS ON), a theatrical interpretation of their early home-recorded EP Psychedelic Swamp. The sold-out four-night run of performances at Union Transfer is one of the trippiest things the Philly indie scene faves have ever done, and as they alluded to when I talked to them last month, the soundtrack to the show was recorded for posterity. Today, the band Tweeted about a free download of the song “Badvertise,” with promises of more to come. You can grab the song right here.
