Joan Jett and the Blackhearts

"I thought we were special."

Double J has still got it! The sultry punk rock veteran is now well into her 50s, but her ability to rock a pair of leather pants and a microphone is without question.

I think that some of the younger set were a bit perplexed by Jett's act, however, as I did overhear one cynic comment: "I don't like Joan Jett enough to stay vertical. I think I might sit down for this set."

Jett at least made an effort to connect with the Millenial Generation, starting her set with a new tune lambasting social media, T.M.I. (Too much information, for those out there unfamiliar with teenage-girl acronyms of the mid-2000s.)

Jett's setlist included a good mix of new stuff, established hits and covers, my favorite being Crimson and Clover.

In between songs, Jett riffed on diverse and compelling topics, from her time spent growing up in Maryland (she's an Orioles fan!), to her desire to be a part of a threesome, to the suckability of brain tumors.

Bonus points for the choreographed fist pumping during Bad Reputation, a song some younger fans might be familiar with since it was used as the intro for Judd Apatow's television series Freaks and Geeks.

There was an awkward moment when Jett's encore ran long and the Dropkick Murphys began drowning her out from across the festival grounds.

I bet there was a fight between them later and someone got their paperboy cap knocked off with a flying leather boot.

Highlights: Bad Reputation, Soulmates to Strangers, I Hate Myself For Loving You

Dropkick Murphys

"Sometimes I was so messed up and didn't have a clue."

Time for the show stopper! Perhaps as a result of spending too many years dealing with disrespectful Red Sox fans at Camden Yards, I'm not a huge proponent of the whole Good Will Hunting/Red Sox Nation scene.

Still, I can appreciate a rocking tune, and I stayed around for the entirety of the Dropkick Murphys 20-song set. It's also kind of refreshing to the ear to go from six hours of guitars and drums to a menagerie of bagpipes, accordions, bozoukis and tin leprechaun whistles.

There was also some good dancing up there on the stage. I assume what I was seeing was an Irish jig of some sort. I just know that it looked like the guy was racking up like 10 million points on Dance Dance Revolution.

A highlight was obviously Shipping Off To Boston, which fellow Bostonites the Mighty Mighty Bosstones joined in on, as well as a wounded veteran, who actually removed his prosthetic leg and used it to encourage the raucous crowd. The band also wished a very special happy birthday to eight-year-old Cameron.

During the encore, they did that slightly annoying thing when like 200 people joined the band on the stage. I don't know. I'm sure it's cool for the people that get to go up there, but for everyone else it's just like "umm, security? Hi?"
