This was not just loud music this morning, it was once again ear-splitting amplified music from the same guys who have been speeding their souped-up Hondas and Acura’s around the South End, revving engines for hours at a time, dumping motor oil and garbage all over Atlantic Street and partying late at night. A serious quality of life problem. Wish the PD would address this issue. Just count the number of complaints from this corner of Atlantic Street
