After his ‘90s alt-soul outfit, Son, got chewed up and spit out by the major-label machine, Jason Beck decamped from Toronto to Berlin and reinvented himself as the louche MC Chilly Gonzales. Alongside electro-rap workouts like “Take Me to Broadway”, he has dropped in low-key keyboard sketches—like “Chilly in B minor”—that betray his classical training. Those particular talents flourish on the meditative Solo Piano series and the string-quartet-enhanced Chambers, while Gonzales shrewdly balances high art and the lowbrow on tracks like “Theme From In-Between”, which couches his tinkling ivories in a boudoir-funk groove.
