Despite his fascination with extremely dense structures, California-based composer Chris Brown is surprisingly tolerant about loosely interpreting them. Chalk it up to being realistic about expectations, or a musical career that has been equally devoted to composing and improvising, but to Brown “the loose comes with the tight.” That seemingly contradictory dichotomy informs everything he creates, whether it’s designing elaborate electronic feedback systems that respond to live performances and transform them in real time or—for his solo piano tour-de-force Six Primes—calculating a complete integration of pitch and meter involving 13-limit just intonation and a corresponding polyrhythm of, say, 13 against 7.
