Why watch football on Monday night—it’s still football season, amirite?—when you can get your metal on at the home of all heshers past, present and future, Launchpad (618 Central Ave. NW) on Monday, Jan. 21. That’s the night that Tetrarch, an alt.metal band who have relocated to El Lay after spending their formative years in a Georgia Swamp play a very noisy and very satisfying gig at this legendary venue. Diamond Rowe’s lead guitar slays and the rhythm section composed of Ryan Lerner and Rubén Limas will shatter your bones, even after repeated exposure. With tuneage like “Disciples of Sorrow” and “Final Words,” listeners are practically guaranteed a fist-shaking, head banging, damn good time. Better yet, local heavy rock gods Ashes of Jupiter are also on the bill, ready to kill. WolfPack Weekend opens. Get thee out, Satan, get thee out! 9pm • $8 • 21+.
