Before breaking up in 2011, Baltimore post-punks Double Dagger recorded a series of songs that ended up never seeing the light of day. This Record Store Day, however, the posthumous group will debut the 333 LP, an album comprised of unreleased tracks.

Featured on the upcoming release will be 'Heretic's Hymn', which splits between Mission of Burma-like chugging bass and drums before spiraling out in a slow melody of feedback and distance. The structure is appropriately fitting, considering the first half sounds ultimately fresh and vibrant, but the latter sounds off as a true swan song.

Along with the LP, the band will be releasing a documentary chronicling the trio's final days entitled If We Shout Loud Enough.
