Variety is the main ingredient for this week’s Buzzards Bay Musicfest. The five concerts span four centuries of music with ensembles ranging from full orchestra to a harp, flute and viola trio. Classical music will be the focus on Wednesday, Thursday, Saturday and Sunday while the Friday night program will feature a 9-piece jazz band. There will be a viola concerto on Wednesday, a clarinet quintet on Thursday and a cello feature on Sunday. World renowned conductor JoAnn Falletta will lead the orchestra while concertmaster, violinist Charles Stegeman will serve as Artistic Director. The musicians come from every corner of our country (musicians from Florida, California, Washington state and New England) and indeed around the world. The concerts are free and held in the air-conditioned Fireman Performing Arts Center on the campus of Tabor Academy, 245 Front St., Marion. Parking shuttle vans from the Sippican School are a free service provided for the Wednesday, Friday, and Sunday concerts. Please visit www.buzzardsbaymusicfest.com/ for more detailed information.
