Though you won't be invited on to the dance floor, if you take in the Gold Coast Players' Rhythm and Shoes concert, you'll at least hear a stylistically varied program that's all about the power of movement and dance – from David Bruce's Gumboots to Astor Piazzolla's Milonga del Angel, to Paquito d'Rivera's Invitacion al Danzon. Tony Striplen, clarinetist at the S.F. Opera, and violinist Laura Albers, the Opera's associate concertmaster, guest star.
