Humor is everything, as Kid Koala has proven in the past. But so is riffage, something Your Mom’s Favorite DJ possesses in abundance compared to its funnier predecessors. The result? A sizzling jam, especially on the three smoking crunchers from his new Seattle project Slew (“Test 1,” “Test 2,” and “Test 3”), which drop fiery blues-hop like sonic hammers. Meanwhile, the mournful piano of “Things’ll Be Good Again” keeps the CD‘s vibe airy and seamless, just the way true-school hip-hop likes it. One of the baddest releases of the year so far.
