The way we see it you can look at Friday the 13th one of two ways; either hide in a dark locked room and wait for midnight and the dawn of July 14th or throw caution to the wind and do something uncommon. Something you just don’t do that often. How about listening to one of the most singular and celebrated voices in Boston rock while cruising the Boston Harbor? Bet you don’t do that every day. Well tonight you can as Dear Leader, the current act formed by Sheila Divine frontman Aaron Perrino, and Aunt Martha, play the “Rock On! Concert Cruise.” This spectacular summer opportunity, particularly given the gorgeous weather, boards at 60 Rowe’s Wharf Boston MA at 7:15, and will depart at 8, returning at 11.
