Machine Head has returned to the crushing sound of their first two albums. Listening to Imperium you know these motherfuckers are back to flatten you. The drums rattle like a gattling guns and Rob Flynn spits venom. This album seems to incorporate a bit of every previous Machine Head release into the songs. Melodic parts are interspersed with extreme aggression. Even though overall the sound leans towards the first two albums, the band opted not to ignore the elements of an album like The Burning Red, which was still a great record.
