Already volume four and we barely had time to blink. But something was different here. The opening track was not an immediate classic, neither was the second track. No this role was reserved to the sweet Changes. But you see, "sweet" is not a word I'm comfortable using in connotation with Black Sabbath, these guys personified evil and Changes sounds like a teenager lamenting about his getting more hair where there was no hair before (I'm not big on analyzing lyrics). This song is followed by an experimental little tidbit called Fx and then... The Black Sabbath I know and love jumps up at me with a driving-down-a-deserted-highway-at-reckless-speed heavy slab of rock called Supernaut. Easily the best track on the album, it's basically pure, untamed energy in aural form and should be consumed in small doses. Two extreme doom tracks worth mentioning are Cornucopia and Under The Sun.
