Redefining the sound of rock itself. Hard and heavy, but also mild and flowy, in a beautiful way. Call it one of the rare episodes of "psychedelic metal", at least as much as the sound can be defined.
Of course, the songs follow a very simple formula which is repeated throughout the album, but who doesn't like 40+ minutes of a groovy vibe? Ultimately, it ends up being an experience. A must listen for anyone looking for a "fresh, new sound".
