Blue Curtain, in co-operation with the Princeton Recreation Department, presents two evenings of free concerts on Saturday, July 15 and 22 at 7 p.m. Both events will present musical traditions. Concerts will be held at the Pettoranello Gardens Amphitheater in Community Park North, Route 206 and Mountain Avenue. Kicking off the 2017 concert series on Saturday, July 15 will be Mystic Bowie, the legendary Jamaican front-man of the TomTom Club; and the New Orleans sounds of Sasha Masakowski and The Sidewalk Strutters. From humble beginnings in St. Elizabeth Parish, Jamaica, Mystic has released five studio albums: “Funky Reggae,” “Rebirth,” “Nevah Kiss and Tell,” “Sweet Jamaica,” and “Money Tree, The Best of Mystic Bowie Vol.1” Beginning in 1992, he was lead vocalist for the TomTom Club, the spin-off band from the Talking Heads, for nearly two decades.
