For those of us who doubted nu-jazz’s staying power, Detroit’s Mr. Arnold opens a can of Oh No You Fucking Don’t. “Anaconda” finds him lacing a crisp and quick Afrobeat-style rhythm with some techno synth action, while on the flip he offers up a boosted cover of Herbie Hancock’s criminally overlooked “Rough,” in which he lands vocalist Ayro into a forest of pure wah. Rude for the dancefloor.
