Copied from their site: "Heavy T.O. doors will open at 11:30AM with performances beginning at 1:00PM. Performances end at 11:00PM." The lineups are too large to do in just the evening I would imagine.
Also this weekend I'm seeing Protest the Hero, Maylene and the Sons of Disaster, and Tesseract on friday (second time seeing this show), a local hardcore show on Saturday night (its the RIP show for a band called King Cobra that has been around forever, a large turnout is expected
), and Rammstein on Sunday at the ACC. f**k. Yeah.
