On July 22 a special, one-time showing of Dara Friedman's movie, Musical, will be presented at Riverside Park South. Dara Friedman's Musical is a 48-minute orchestration of 60 singing performances that took place on the streets of Manhattan last fall, commissioned by Public Art Fund. For three weeks, Friedman invited ordinary New Yorkers to burst into song on street corners, in coffee shops, museums and train stations. This film records those performances, creating a sprawling American musical.
