A more thoroughly Latin-flavored Black Eyed Peas, the Los Angeles-based Ozomatli may actually be even more fun and festive. And then there is its advanced level of prestige: Ozomatli has been designated an official U.S. State Department Cultural Ambassador, representing L.A. and a melting-pot U.S. to the world. The 14-piece orchestra Chopteeth Afrofunk Big Band, inspired by Fela Kuti's Afrobeat sound, opens. Saturday, Jan. 21. Doors at 9 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $25.
