The Polyphonic Spree, a symphonic pop ensemble from Dallas, Texas, have turned a corner with their new record, The Fragile Army. They replaced their Technicolor holy-roller robes with dour black paramilitary fatigues and gave their music grim tones to match. Where the soft '70s radio sunshine of their previous records could be overwhelmingly twee, their new album is a battle between light and dark. The Spree have always been a terrific live spectacle; now they have a record worthy of their pomp. (Showbox, 1426 First Ave, 628-3151. 8 pm, $23 adv/$25 DOS, 21+.)
