A rap career seems like an odd move for a classically-trained pianist, but Kev Choice has figured out how to make it work—often in startling ways. His latest release is a spin on "Arietta" (Opus 12-1), a classical piece by Norwegian composer Edvard Grieg. Choice delivers a rap serenade to a fictional love interest, while playing Grieg's piece—the original, not a chopped-up sample— on acoustic piano. Equal parts classical and hip-hop, it's completely unorthodox with respect to both genres. And yet it's a bold move on Choice's part. He's obviously got chops.
