Black Sabbath - Master Of Reality & Vol.4 (1987) [33PD-354, Japan]

The shortest album of Black Sabbath's glory years, Master of Reality is also their most sonically influential work. Here Tony Iommi began to experiment with tuning his guitar down three half-steps to C#, producing a sound that was darker, deeper, and sludgier than anything they'd yet committed to record. (This trick was still being copied 25 years later by every metal band looking to push the limits of heaviness, from trendy nu-metallers to Swedish deathsters.) Much more than that, Master of Reality essentially created multiple metal subgenres all by itself, laying the sonic foundations for doom, stoner and sludge metal, all in the space of just over half an hour. Classic opener "Sweet Leaf" certainly ranks as a defining stoner metal song, making its drug references far more overt (and adoring) than the preceding album's "Fairies Wear Boots." The album's other signature song, "Children of the Grave," is driven by a galloping rhythm that would later pop up on a slew of Iron Maiden tunes, among many others. Aside from "Sweet Leaf," much of Master of Reality finds the band displaying a stronger moral sense, in part an attempt to counteract the growing perception that they were Satanists. "Children of the Grave" posits a stark choice between love and nuclear annihilation, while "After Forever" philosophizes about death and the afterlife in an openly religious (but, of course, superficially morbid) fashion that offered a blueprint for the career of Christian doom band Trouble. And although the alternately sinister and jaunty "Lord of This World" is sung from Satan's point of view, he clearly doesn't think much of his own followers (and neither, by extension, does the band). It's all handled much like a horror movie with a clear moral message, for example The Exorcist. Past those four tracks, listeners get sharply contrasting tempos in the rumbling sci-fi tale "Into the Void," which shortens the distances between the multiple sections of the band's previous epics. And there's the core of the album – all that's left is a couple of brief instrumental interludes, plus the quiet, brooding loneliness of "Solitude," a mostly textural piece that frames Osbourne's phased vocals with acoustic guitars and flutes. But, if a core of five songs seems slight for a classic album, it's also important to note that those five songs represent a nearly bottomless bag of tricks, many of which are still being imitated and explored decades later. If Paranoid has more widely known songs, the suffocating and oppressive Master of Reality was the Sabbath record that die-hard metalheads took most closely to heart.

Vol. 4 is the point in Black Sabbath's career where the band's legendary drug consumption really starts to make itself felt. And it isn't just in the lyrics, most of which are about the blurry line between reality and illusion. Vol. 4 has all the messiness of a heavy metal Exile on Main St., and if it lacks that album's overall diversity, it does find Sabbath at their most musically varied, pushing to experiment amidst the drug-addled murk. As a result, there are some puzzling choices made here (not least of which is the inclusion of "FX"), and the album often contradicts itself. Ozzy Osbourne's wail is becoming more powerful here, taking greater independence from Tony Iommi's guitar riffs, yet his vocals are processed into a nearly textural element on much of side two. Parts of Vol. 4 are as ultra-heavy as Master of Reality, yet the band also takes its most blatant shots at accessibility to date – and then undercuts that very intent. The effectively concise "Tomorrow's Dream" has a chorus that could almost be called radio-ready, were it not for the fact that it only appears once in the entire song. "St. Vitus Dance" is surprisingly upbeat, yet the distant-sounding vocals don't really register. The notorious piano-and-Mellotron ballad "Changes" ultimately fails not because of its change-of-pace mood, but more for a raft of the most horrendously clichéd rhymes this side of "moon-June." Even the crushing "Supernaut" – perhaps the heaviest single track in the Sabbath catalog – sticks a funky, almost danceable acoustic breakdown smack in the middle. Besides "Supernaut," the core of Vol. 4 lies in the midtempo cocaine ode "Snowblind," which was originally slated to be the album's title track until the record company got cold feet, and the multi-sectioned prog-leaning opener, "Wheels of Confusion." The latter is one of Iommi's most complex and impressive compositions, varying not only riffs but textures throughout its eight minutes. Many doom and stoner metal aficionados prize the second side of the album, where Osbourne's vocals gradually fade further and further away into the murk, and Iommi's guitar assumes center stage. The underrated "Cornucopia" strikes a better balance of those elements, but by the time "Under the Sun" closes the album, the lyrics are mostly lost under a mountain of memorable, contrasting riffery. Add all of this up, and Vol. 4 is a less cohesive effort than its two immediate predecessors, but is all the more fascinating for it. Die-hard fans sick of the standards come here next, and some end up counting this as their favorite Sabbath record for its eccentricities and for its embodiment of the band's excesses.
