"Some works quietly become masterpieces: Morton Feldman's intense, spare and evocative Rothko Chapel (written for the octagonal building in Houston that houses his paintings) was challenging when new ... Now it seems an utterly natural, hieratic procession of contrasted friezes in which not a note is out of place ... After this half-hour immersion, anything else might be an anti-climax, but the sequence that follows of Erik Satie piano pieces (Sarah Rothenberg) and John Cage choral fragments (Houston Chamber Choir) traces a hypnotic line of innovation".
