When a musical act has the word “experiment” in its name, you can assume you’re in for something out of the ordinary, and potentially in conflict with mainstream tastes. While Calls, the debut feature from the Robert Glasper Experiment, certainly lives up to the first part of that formula—it ain’t your average R&B joint—all but the narrowest-minded listeners should be able to appreciate its mellow, cozy vibe. The collective’s production, a keyboard-driven groove with a subtly shifting time signature, accompanies Grammy-winning soul songstress Jill Scott as she celebrates a man who never fails to pick up when she’s on the line. Feeling it? More innovative, ear-pleasing cuts await on RGE’s Black Radio 2 LP, due out October 29, via Blue Note Records.
