Graveyard’s 2007 eponymous debut album introduced the band as longhaired Swedes bent on blasting proto-metal from towering amps. Then Graveyard's 2011 sophomore LP, Hisingen Blues, rocked with noticeably more bluesy riffs, sounding like early Fleetwood Mac with a distortion-pedal endorsement. The band blends both influences into its third studio album, Lights Out, while offering a slight evolution of the stoner-rock sound. Frontman Joakim Nilsson has found his voice in “An Industry of Murder,” flirting with falsettos, building a subtle tension between his softer sung verses and confidently howled choruses. “Slow Motion Countdown” makes good on its title with plodding rhythms. But rather than take the predictably sludgy route, the band laces the tune with a piano's darker notes and plenty of negative space. Nilsson’s softer sung moments here reside between The Doors’ “Crystal Ship” and Danzig’s “Soul on Fire.” The nearly danceable “The Suits, the Law & the Uniforms” grooves on an upgrade of ‘70s Southern boogie rock, save for some unpredictable free-jazz saxophone and octave vocal harmonies.
