Dropkick Murphys.

It was 2004, and, for perhaps the first time in his life, Ken Casey of Dropkick Murphys was at a loss for words. As far back as anyone in Boston could remember, the band’s co-founder, co-frontman, bassist and de facto leader had been the city’s best-known mover, shaker and hustler.

“I always just felt like I knew everyone in this town,” Casey remembers. “Even before I was in a band, I’d be booking all-ages punk shows at The Rat, which was like our CBGBs. The Boston punk scene was just exploding.”
