Hopefully, it wasn’t the departure of drummer Vince Rogers (who quit the band to pursue a career in mathematics) that made Tera Melos “eschew” math rock. The fact remains that the formerly instrumental experimental outfit is cited as one of the genre’s true innovators. Formed in California in 2004, Tera Melos officially became “big in Japan” last year when Drugs/Complex (a compilation that borrowed from two previous US releases), and Parabolica Jam ’09 (a DVD released by their Japanese label) dropped there, coinciding with a headlining tour that added to their pre-existing cult status. Straight from the horse’s mouth, Tera Melos’ latest album is “densely layered with goodie bits … lots of skronky blip sounds, electro snare rolls, and melodies hidden all over the place.” Not surprisingly, the four-piece behind 2010’s Patagonian Rats channels the Pied Piper by luring gritty, local noise-makers We the Granada (9:30pm), Daytes (10:15pm), the Grasshopper Lies Heavy (11pm), and Zorch (11:45pm) out of their cages before taking the stage just after midnight. $8, the Korova, 107 E Martin, facebook.com/thekorova.
