I'm not going to suggest any new albums because my favourite two were already suggested by Cloudy.
However, i'm going to suggest 3 totally unrelated bands that may be of your liking if you're into Sepultura. First one, on the metal side of things is Entombed. Second one is Ratos de Porao, which is another Brazilian band that blends Trash Metal and Punk in one. It's one of the most powerful acts i know of. Third one is one of the better known NY hardcore bands, Sick of it All. I don't know if you already know all of them as they're not unknown by any means, but in case you don't check them out.
