The song will appear on the band's upcoming digital and vinyl release, Black Feathers, which is due out November 16th, 2010. The instrumental band has featured members of Black Flag, Descendents, Rise Against, Toadies, Hagish, Only Crime, True Widow and more. The artwork for the EP (seen here) was painted by James O'Barr (creator of The Crow graphic novel).
