Just happened to come across these guys a few weeks ago on youtube. From what I've seen the singer is quite an intense performer and has got a hell of a yell. They're touring quite a bit so if you dig check 'em out! Free show in Philly May 6.

They've also done a Daytrotter session.
New album dropping soon... Spirit of Minneapolis... here is a stream of the new album... hoping they make it back somewhere close... their last show in Harrisburg had a terrible turnout... but it was Mother's Day... Straight up stomping rock and roll... definitely worth a listen! These guys would kick some major ass opening for MMJ!
