Two of Vol. 4’s ten tracks have found enduring second lives as storied covers by other acts. The rollicking, science-fictional “Supernaut”—like an inverse “Iron Man,” it’s about a voyager through space and time who’s actually enjoying the trip—received a thrashing industrial makeover at the hands of a dubiously named Ministry side project dubbed 1,000 Homo DJs by Jim Nash, the (gay) head of their record label WaxTrax!. (Hold out for the version with vocals by Trent Reznor, which wound up suppressed by his old record label for years.) On the other end of the sonic spectrum, the moving piano ballad “Changes” was converted into a gut-wrenching soul scorcher by singer Charles Bradley, who transmuted its lyrics about a dissolved romantic relationship into a lament for his late mother. Blessed with one of Iommi’s wickedest riffs and Osbourne’s most vulnerable vocal performances, respectively, the original versions of both songs can stand next to these excellent reinterpretations without being eclipsed; Ward’s carnival-like percussion breakdown in “Supernaut” in particular feels like finding a prize in the song’s otherwise thunderous Cracker Jack box.
