Although the Bang! Festival this past November didn't blow up like organizers had hoped, those who did show up, and stuck it out until the end, got their money's worth. Looking like Cirque du Soleil on acid, New York-based electro-pop group Fischerspooner was the antithesis of the stand-and-spin DJs who had been working the turntables all day. The band and back-up singers appeared first in kaleidoscopic unitards. Then lead singer Casey Spooner was wrapped in white, gauzy bandages, which dancers then unraveled. Costume changes, stage antics that included climbing scaffolding, and general flamboyance -- Spooner and his entourage never let the energy level dip below 500 bpm.
