Not exactly metal, the first one, a bit more HC. But it's good.
Members from Dying Fetus broke off and this was the result.
They're really good, very political, or criticizing might be the right word.
Tune low, play slow.
Another banger.
and the last one is a crust punk band, but it's the singer from At The Gates, Tomas Lindberg.
Probably one of the best metal singers, and definitely in top of crust singers, IMO.
