The CD doesn't do them justice. I have been a fan for years now. Their HBO episodes are way better than just listening to the CD. They are on HBO Zone from time to time, try to catch them!
They have way more awesome songs from the episodes that they play live but that aren't on the CD. They also play some covers with their own little D flare when they play live.
Don't see them open though, catch them when they are headlining. They will go from 1-2hrs rocking your socks off.
