After the 77-member percussive spiral galaxy that assembled beneath the Brooklyn Bridge last summer, it might seem like a comedown to witness Japanese psychedelic drum-circle emissaries Boredoms with only their core members. But even with just three drummers, Boredoms are a force to be reckoned with, and tonight's "in the round" set-up surely adds another element of drama. Squad leader Eye stands behind a towering array of mounted guitars and tabletop electronics, leading the ensemble through pastoral cymbal washes, thunderous tom-tom runs, and Sunny Murray-worthy free-form jams with unrivaled precision and intensity.
