A kinder and gentler Zorn, exploring a sound world not unlike those pioneered by composers Giacinto Scelsi, Morton Feldman and Olivier Messiaen. Acoustic, minimal/ambient music of unusual subtlety and beauty, inspired by, and dedicated to the work of artist Agnes Martin. "Redbird," a hypnotic work for harp, violin, cello and percussion mirrors the detailed and complex painting for which it is named, as a series of chords are ordered and reordered, creating a play of memory and surprise that will leave the listener in a sensual reverie. It's difficult to believe that "Dark River" for four bass drums is actually acoustic music; the interplay of sonorities reminds one more of tape manipulation or the electronic beating of underwater sonar.
