Skindred is a band from all over the UK that has described their style as "reggae metal". Really, it's more of a mix of metal, punk, reggae and what ever else they feel like throwing in. I saw these guys open for Disturbed a number of years ago, and they pretty much stole the show. If you're lucky enough to be in the UK right now, I believe they are opening for Rob Zombie on his current tour.
Here is a track, Pressure, from their freshman album, Babylon. I will say that the sound quality isn't the best, but it's all I could find on Youtube.
Next is Trouble, from their album, Roots Rock Riot.
And lastly, we have the opening track, Stand For Something, from their latest album, Shark Bites & Dog Fights.
Also, take note that if you like these guy's they have a new album dropping this year called, Union Black.
