It may not yet be hip enough to merit an evening of lessons at Lulu’s Club Mardi Gras, but the centuries-old Hungarian folk dance csardas fits all the requirements for an American dance craze. It’s as suggestive as salsa, as much a rebellion against classical dance forms as swing was when it first erupted in urban dance halls, and every bit as hot ‘n’ heavy as the Argentine tango. Tonight’s “Csardas! The Tango of the East” presentation features the dancers and musicians of the Budapest Ensemble performing a danceography of Eastern Europe’s most popular dance form. The evening of fiery gypsy music promises to have us all jumping, jiving, and wailing csardas-style soon enough, so get on the bandwagon now. When Meeps starts carrying verbunk-dancing boots and Budapest Ensemble Artistic Director Zoltan Zsurafszki dethrones Brian Setzer, you’ll be ready. At 8 p.m. at George Mason University’s Center for the Arts Concert Hall, 4400 University Drive, Fairfax. $25-$35. (703) 993-8888. (Amanda Fazzone)
