Bands that come to mind are In Flames, Children Of Bodom, (classic) Sepultura, Fear Factory, Napalm Death and even Therapy? (the latter mainly in the sound of the drums). Vocals range from brutal grind growls to melodic clean chants, each of them perfectly suited for the musical passage accompanying it.
Musically, you can expect a more than decent variation between brutal in-your-face death riffs and highly melodic passages of blissful headbanging. It's clear that these are seasoned musicians with a flair for the entire history of extreme music. It's the new soundtrack for whenever armageddon comes...
