Say what you want about the movie itself, the music is good as hell. The limited run cassette contains 12 songs featured in the documentary, including tracks from Floodplain, Jedi, Dead History (fea. Matt Rezac and Brock Specht of Floodplain), and Beehive Vaults, a late 90s project featuring Shawn Kock and Nathan Thelen (Splay 120, Pretty Girls Make Graves, Drug Cabin). Some of these have never been released anywhere.
No worries if you don't have a tape deck, each cassette also comes with a digital download card.
