Belly dancing requires physical focus, strong rhythm, and a good dose of soul. The Valley-based Crescent Dancers, who perform onstage as well as at regional fairs, parties, and events, craft their shows by combining cabaret-style belly dances and village folk dances, all set to music and inspired by Middle Eastern dance traditions. If this art has ever enchanted you and you’re interested in trying it out, the troupe is offering a free performance and workshop for all ages this week. Come dressed ready to move.

Crescent Dancers: Sunday, March 27, noon. Free. Pelham Library, 2 South Valley Road, Pelham, (413) 253-0657.
