With their idiosyncratic blend of spiraling guitar riffs, fuzzy vocals, and grimy insouciance, the Strokes are still tied to the early aughts, when their debut set a new standard for DIY rock ’n’ roll. So it’s fitting that the outfit’s first music since 2013’s “Comedown Machine’’ is a trip down memory lane. The four-track “Future Present Past’’ EP (really three songs, plus a dreamy remix) kicks off with “Drag Queen,’’ a humming, heaving beast of a track awash with swelling guitars, lazy synths, and marching drums. It’s a continuation of their 2010s sound that kicks like a “Room on Fire’’ cut but feels eerie and restrained in a manner indicating an amorphous evolution. “OBLIVIUS’’ presents the band in more predictable form, relying on “Comedown’’-style guitar play and Julian Casablancas’s raw voice. But “Threat of Joy’’ is the EP’s most exciting discovery, an exuberant throwback to “Is This It’’ that glides and glimmers with off-the-cuff conviction. That song, more than the adventurous opener, gives you hope for the future of a band long plagued by discord and doubt. Finally, the Strokes sound as if they’re having fun again.
