After making serious noise in the modern funk scene, XL Middleton makes a return to the g-funk/hip hop sound that marked his earlier work with the single “Cool Minute.” It’s a funked out, synth-heavy rap song with an equal amount of appeal for the modern funk world or the underground legions of g-funk fans that put XL on the map originally. Those familiar with his most recent albums, “Tap Water” and “Things Are Happening,” will recognize the signature synth leads and intricate analog bass lines.
