Come to the PS/21 Performing Arts Center for the Friday Swing dance series. As always at PS/21, the emphasis is as much on the music as it is on the dancing. The music is always live, the styles are variable, and the ambiance is second to none. If you value world-class live music, and if you enjoy a cabaret setting and the opportunity to be with old friends and meet new ones, you’ll enjoy this dance. Alan Thomson’s Little Big Band or Berkshire Bop Society (Lincoln Mayorga, Otto Gardner, Sheri Bauer-Mayorga and Sam Zucchini). The dance as are all performances is held inside an ultra-modern tent atop a hill in an old orchard in Chatham. The tent (the term doesn’t do justice to the wonderfully designed clamshell-shaped structure) will remain in operation for a few years until the permanent structure is completed. It’s cool on a warm evening, comfortable on a brutally hot evening (lots of fans), and the setting is perfect. Dancing is on a raised stage in the back of the tent with seating for an audience in front of the stage and for the live music performers to one side. Season tickets will also be available for those who don’t mind saving a few bucks. (Swing Dance Season Pass $50 general admission / $40 members.) But even so, for the regular admission you get great live music and fine dancing. Admission includes instruction from 7-7:30 “We provide non-alcoholic refreshments and light snacks at no extra charge. Dancers may bring their own choice of beverages. We also provide plenty of table seating for those times you just want to sit out and enjoy the music and the company.” For more information Warren Collins or call 518-392-6121.
