“Friday night [at the Montreal Jazz Festival, acoustic/electric bassist Stanley] Clarke teamed up with the Harlem Quartet, a cutting-edge modern classical group that not only proved itself capable of nailing Clarke’s complex charts but also demonstrated great capacity for content-rich improvisation. This wasn’t the kind of string section that pads and sweetens; [The Harlem Quartet] collaborated with Clarke as an artistic entity that displayed top-notch chops, sensitive ears and surprising guts.”
