Not all of this, incidentally, was rendered in La Brea sinks of lugubrious bass blasts - several of the songs had high wailing solos and interesting changes of tempo, and "Paranoid" really moved. If you took the trouble to listen to the album all the way through.
Master of Reality both extends and modifies the trends on Paranoid. It has fewer songs, if you discount the two short instrumental interludes, but it is not that the songs are longer than the first record - the album is shorter. The sound, with a couple of exceptions, has evolved little if at all. The thick, plodding, almost arrhythmic steel wool curtains of sound the group is celebrated and reviled for only appear in their classical state of excruciating slowness on two tracks, "Sweet Leaf" and "Lord of This World," and both break into driving jams that are well worth the wait. Which itself is no problem once you stop thinking about how bored you are and just let it filter down your innards like a good bottle of Romilar. Rock & roll has always been noise, and Black Sabbath have boiled that noise to its resinous essence. Did you expect bones to be anything else but rigid?
The rest of the songs, while not exactly lilting, have all the drive and frenzy you could wish for in this day and age. Thematically the group has mellowed a bit, and although the morbidity still shines rankly in almost every song, the group seems to have taken its popularity and position seriously enough to begin offering some answers to the dark cul-de-sacs of Paranoid. "Sweet Leaf," for instance, shows that Black Sabbath have the balls to write a song celebrating grass this late date, and the double entendre, if you can even call it that, is much less tortuous than it would have been in 1966, with an added touch of salvation from grosser potions: "My life was empty forever on a down/Until you took me, showed me around ... Straight people don’t know what you’re about..."
Unfortunately, the religious virus also rears its zealot head, in "After Forever," which is a great Yardbirds-type arrangement nevertheless and despite its drubbing us over the head with "God is the only way to love" it does have the great line "Would you like to see the Pope on the end of a rope?"
And besides, isn’t all this Christian folderol just the flip side of the Luciferian creed they commenced with and look back on balefully in "Lord of This World"? And for those of us, like me, who prefer the secular side of Black Sabbath, there’s "Solitude," a ballad as lovely as any out of England in the last year (with flute yet), and "Children of the Grave": with "Revolution in their minds the children start to march Against the world they have to live in Oh! The hate that’s in their hearts They’re tired of being pushed around and told just what to do. They’ll fight the world until they’ve won and love comes flowing through."
