Ball of Wax, Volume 28 (out now, self-released, ballofwax.org): Levi Fuller’s BOW compilations are always stellar, but he may find it hard to top himself after this edition–booty-shakin’ tracks of the electro variety (including new projects from Josh Morrison and Robb Benson) that flow together like your favorite summer playlist.MA’CHELL DUMA LAVASSARBattleCry Melody, Vanquish (out now, self-released, battlecrymelody.com): If the Bloodhound Gang were virgins, they’d sound like BattleCry Melody. Not that these funky white-boy rappers should be taken home to your mother. Quite the contrary. However, somehow, this acoustic guitar-fused hip-hop is oddly satisfying and genuine. JOE WILLIAMS
