Nashville Shakespeare Festival’s annual celebration of the Bard’s birthday (No. 449) moves from Centennial Park to the downtown riverfront, and this year also pulls double duty as a party in honor of the company’s silver anniversary. For the third consecutive year, NSF artistic director Denice Hicks will stage the “biggest balcony scene ever,” featuring a Globe Theatre’s worth of would-be Romeos and Juliets. (Scripts will be available for participants, and the play-acting commences at 3 p.m., with Hicks serving as dialogue coach.) It all takes place in Cumberland Park — on the east side of the river near the Shelby Street Pedestrian Bridge. There will be room for the kids to frolic and ample parking. Early birds get a shot at a limited number of free birthday cupcakes, and various food trucks will be on site as well. The music lineup includes The Mabels and Adam Burrows, and DJ IndieChris will be spinning later in the evening. Other upcoming NSF events include the April 26-27 auditions for the 2013 Shakespeare in the Park production of A Midsummer Night’s Dream (Aug. 15-Sept. 15), and the May 4 Shakespeare Allowed reading of Henry IV, Part 2 at the Nashville Public Library.
