After shattering the mouthpiece he had used for years, tenor saxophonist Ivo Perelman searched for a replacement, choosing the same mouthpiece used by Paul Desmond, provoking a shift in style to more melodic lines, as heard in this studio album performed with the exemplary quartet of pianist Matthew Shipp, double bassist Mark Helias and drummer Tom Rainey.

Four extended collective improvisations of implicit lyricism and transcendent power from Brazilian-born New York-based tenor saxophonist Ivo Perelman, recording in the studio with his quartet of frequent collaborator and masterful bassist William Parker, also performing on shakuhachi, along with pianist Christopher Parker and drummer Chad Anderson.
