The Doppelgangaz, an upstate New York rap duo consisting of EP and Matter Ov Fact, have been cultivating a cult rap fanbase since 2008’s eerie The Ghastly Duo EP. Now onto their seventh full-length, Peace Kehd, due to be self-released on February 18, the pair build on the buzz of last year’s excellent HARK album, but supplement the project’s endearingly static-sodden beats for a slicker sound. (The progression is reminiscent of when Masta Ace’s synth-inflected Sittin’ On Chrome followed the rugged charms of SlaughtaHouse.) The rappers use bucolic production as a backdrop to reel off rhymes that offer insight into an off-kilter world, one that delights in mixing references to gourmand foodstuffs with the sort of sexual perversions that would make Dr. Octagon smirk. As a result, Peace Kehd is another successful update of the Doppel gospel.
