All the way from South Africa, prepare to be blown away Thursday, Feb. 18, at 8:00 p.m. in the Sellersville Theater (PA). Ladysmith Black Mambazo, with their harmonies, counterpoint, vocal acrobatics, choreography and consummate showmanship results in a rollicking evening with nary an instrument played. Famous before they appeared on Paul Simon’s Graceland, they were superstars afterwards. The cool thing is about the Sellersville Theater is that it’s connected to The Washington House, a great classic restaurant where they let you bring your drinks on the wooden walkway right into the show. You can also catch Ladysmith Black Mambazo at Town Hall in New York City on Feb. 19 and the Richardson Auditorium at Princeton University on Feb. 20.
