The Brooklyn sing-rapper Santogold, who I’d tried and failed to see the night before, didn’t have anything like I Wayne’s bass sound. She didn’t have his voice either; hers is more chirp than coo. And most of her tracks had none of the facepunch immediacy of “Creator,” her utterly unstoppable new single.

Still, she had a totally disarming stage-presence, she and her hype-woman awkwardly and enthusiastically flailing limbs in all directions, like 12-year-olds making up on-the-spot dance-routines while watching MTV. Santogold’s been racking up a pile of M.I.A. comparisons lately, and she works with a lot of the same producers and stirs up a lot of the same influences. But where M.I.A. is a cold, harsh performer, Santogold is dizzy and overjoyed.

Her background is in ska-punk, not in hanging out with Elastica, and plenty of bubblegum alt-rock creeps its way into her tracks alongside dancehall and rap and techno and whatever else. From yesterday’s evidence, she’s still finding her stage-legs, but she doesn’t necessarily need them yet. She didn’t amaze, but she was fun, something I could say about any number of CMJ acts this year.
