It’s only been a month since Circuit launched this Thursday soirée at Grass, but already most of Miami's mod squad has made it their prime hangout. Maybe it's the mashup company, which includes hip-hop heavies and indie-art radicals; maybe it's the mainland locale, which saves everyone a trip 'cross the causeways; or maybe it's just that these cats know how to throw one hell of a party. Dress wise, crack wiser, and leave your biases at home.
