Grateful Dead Concert Cruise

Rock On!'s sixth annual Grateful Dead concert cruise hits the Harbor with Boston's best tribute band, Playin' Dead. The six-member group boasts former members of Dark Star Orchestra, The Knot and Uncle John's Band, who recreate the look, sound and vibe of the legendary live band as they take on Jerry Garcia and the guys' jam classics like "Fire on the Mountain," "Truckin'," "Sugaree" and more. The three-hour trip features an open-air deck with an on-board snack stand and cash bar.
