Join us at Trum Field on Thursday, June 28, for music, fun and fireworks. As part of Somerville’s annual Independence Day festivities, the 215th Army Band will perform along with Booty Vortex, a local disco-funk band. Performances start at 6:30 p.m., and fireworks will begin around 9:15 p.m. Streets around Trum Field will be closed to vehicle traffic, and buses will be rerouted to make space for the crowds.
