Here's one more people should be in to....
Flogging Molly. A band of seven people playing a fusion of Irish punk rock, and folk music. Sometimes the moods and tones of the songs sway heavily in one direction or the other. Sometimes, you don't know what else to call it... but good.
I've got four of their five released albums.
Alive Behind The Green Door
Within A Mile Of Home
Whiskey On Sunday <---- The one I don't own.
The live shows put on by this band are notoriously fun and rowdy. And drunken for that matter. Flogging Molly attracts mostly people 17 and up to their shows, and often has 21 and up shows were almost everyone drinks pint after pint of Guinness Draught. The best part about these shows is the camaraderie and how everyone gets along as they sing and dance together. No doubt you'll find a group of people jigging not too far from the mosh pit, and you'll hear everyone in the crowd singing along.
