Burning Spear. When most people think of reggae, their mind immediately goes to Bob Marley & The Wailers, but the Spear has been Burning since 1969. They're still going strong, I saw them live recently at a small venue in my town. I don't know if they're underrated, but no one I know has ever heard of them.

Dropkick Murphys. Well known in the punk world, but not really to the rest of the music world. Their famous bag-piper (yes bag-piper), Spicy McHaggis recently left the band because he was getting married and had other interests, but they're still going strong.
