From bebop to Detroit soul to hip-hop, the music may change but the command remains the same: shake! We can only guess that the Arab Dance Seminar will trace this tradition back to the ancients. The weekend of events includes lectures and performances at the Cambridge YWCA (7 Temple Street, Cambridge, 617.661.9622) and classes with live musicians at the Dance Complex (536 Mass Ave, Cambridge, 617.547.9363). Try it out, learn some history, and feed your appetite for seduction. Dance experience is highly recommended. For times, fees, and registration, visit www.arabdanceseminar.com.
