Le Loup are an apocalyptic future-folk ensemble from the District of Columbia whose debut album—on Sub Pop spin-off Hardly Art—bears the unwieldy but evocative title The Throne of the Third Heaven of the Nations' Millennium General Assembly. Their songs reference Dante's infernal cantos, noisy natural phenomena, and the rapture. The music sounds like what a band might play on your back porch while the sky swirled into a black vortex and your neighbors ascended to heaven—spare, tense, and atmospherically turbulent. (Chop Suey, 1325 E Madison St, 324-8000. 8 pm, $8, 21+.)
