What’s a white, British techno artist doing coming off like a real-deal classic-soul throwback? Who knows, but it works on Multiply; Jamie Lidell absorbs Stax/Motown and disco grooves and regurgitates them as a joyful tribute. The title track is his own ”Superstition,” and R&B slow burners gladly trade space with cheeky future-funk workouts. If even a hint of Jamiroquai makes you gag, stay away; otherwise, proceed to the dance floor, please.
