"For much of the later '60s and '70s, the most intuitive improviser of his generation was obliged to teach improvisation to college students, gigging only in relative obscurity. Randy Kaye was a loyal and dependable supporter in those days, and he adds just the right kind of softly enunciated percussion to Giuffre's '80s quartet albums. Bob Nieske's 'The Teacher' pays no less a tribute. Scored for Giuffre's bass flute, it has a crepuscular, meditative quality that isn't altogether typical of a lively and almost self-consciously contemporary set. Levin's keyboard stylings are perhaps a little too blandly atmospheric, but they open up the texture for Giuffre's familiar chalumeau clarinet and surprisingly agile soprano saxophone. The earlier QUASAR is equally fine and the writing may even be a little better."
