www.mansionmiami.com After Level was purchased by the Opium Group, renovated, and renamed Mansion, this linchpin of South Beach nightlife has become the place for excited celebrity-seekers thanks to the many models and hip-hop stars it draws. It also has frustrated those gawkers with its strict velvet-rope policy. Lost in the commotion is the fact that it is a superior music venue, capable of holding 2500 people throughout its two floors and four rooms. Since its March 2004 opening, Mansion has hosted an amazing concert by hip-hop band the Roots; a raucous performance by hard rock supergroup Velvet Revolver; and Hip-Hop Fridays, an occasional concert series co-promoted by Empire Events and featuring old-school rap legends Big Daddy Kane, the Jungle Brothers, and Black Sheep. With a mixture of plush seating and standing areas and an excellent lighting and sound system, Mansion is a seeming contradiction -- a snooty SoBe club and a great place to see live bands.
