Of Montreal, the non-Canadian, pro-vaudevillian, Ziggy Stardust-esque troupe from Athens, Ga. present vibrant, synth-driven, flamboyant energy that feeds off the glittery residue of Queen, Bowie and Prince. Their sound -- gleeful, spastic and psychological stunning -- is as complex as anything Henrik Ibsen ever wrote, fraught with tension and relief, color and charm. Their albums are the equivalent of watching the best Rock Opera ever and then dying immediately afterward. They play the Madison Theater with Fire Zuave and Sugar and Gold.
