Tropicalia, the dance club hidden underneath a Subway sandwich shop on U Street NW, is celebrating its fourth birthday the way it started: with international dance music. While the club is sometimes home to DJs playing American pop hits now, on this anniversary, U.K.-based Dhol Foundation will bring its booming South Asian percussion and rhythms to the small room. The combo is led by Johnny Kalsi, who’s also played with Afro Celt Sound System and Transglobal Underground. His instrument, the dhol, is a barrel-shaped drum with a goatskin top and bottom that the drummer hits with a stick and a beater. And the Foundation often features four of them, because Kalsi likes a big, multicultural wall of sound approach. The Dhol Foundation performs with DJ Rekha at 8 p.m. at Tropicalia, 2001 14th St. NW. $20–$25. (202) 629-4535. tropicaliadc.com. —Steve Kiviat
