Tonight, sludgy local postrock five-piece Anatomy of Habit celebrate the release of their Relapse Records debut, the epic and excellent Ciphers + Axioms, at the Empty Bottle. The record is made up of two album-length songs, and today’s 12 O’Clock Track is “Radiate and Recede,” the disc’s A-side. It’s a massive, swinging, slow-burning track that gradually builds from a disjointed, clanky spoken-word piece into a full-on heavy-metal battering ram careening out of control. The song’s 20 minutes may take up most of your lunch break to get through, but the chilling, explosive climax is more than enough payoff. Check the song out below, and see the band live tonight.
