Kayo Dot is a metal band, though you might not guess it from the first half of Choirs of the Eye, the 16-member “project”’s debut release on John Zorn’s experimental Tzadik label. That’s because the Dot—formerly known by the unfortunate, UPN-esque moniker Maudlin of the Well—spends the first 30 minutes of Choirs spanning the gamut from melancholic pop to pagan folk to 20th-century classical. Jack of all trades, master of none, right? Wrong: By all that’s unholy, the diminished chords fall like rain once the guitarists finally crank their amps and get to shredding midway through Track 3 (out of five), “The Manifold Curiosity.” And this isn’t any chin-stroking avant-garde approximation either, mind you, but real-life, sulfur-stink, down-tuned crusty doom. Yes, indeed, Kayo Dot is a metal band. It plays with the Medications and Biolich at 8 p.m. at the Warehouse Next Door, 1017 7th St. NW. $7. (202) 783-3933. (Brent Burton)
