After four albums of proggy complexity and dark themes, British heavy-metal pioneers Judas Priest stripped away the fat and donned their now-iconic leather, handcuffs, and studs for this torrid, fist-pumping 1979 album. Singer Rob Halford revels in S&M imagery over the grinding blues-rock of “Evil Fantasies.” The title track is a fiery anthem with driving riffs and an epic guitar solo, while the rumbling drums of “Take On the World” fuel an inspiring call to brotherhood.
