Unreal as it may seem, apparently people did make music in Brooklyn before mid-2007. Were we to buy into this preposterous idea, then among the mythic first wavers we might hypothetically have to count would be Gang Gang Dance. Prolific, arty, and intermittently funky, they may seem more like contemporaries of earlier NYC-based punk-funkers like the Rapture, but the band's latest offering, Saint Dymphna, sees them happily in the fold of the brain-frazzling disco of MGMT. Disorientating for certain, this one-off is likely to be entrancing, nonetheless.
