Meeting at Park West Studios in Brooklyn, the NY trio of Ivo Perelman on tenor saxophone, Mark Helias on bass and Tom Rainey on drums record seven collective free improvisations of great depth and expression, unhurried playing that concentrates on the group dialog, yielding space for exceptional soloing supported by perceptive interaction; masterful!

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.

Bringing decades of experience from far-reaching careers as leaders and in collaboration with some of the most luminary improvisers in creative jazz, this first meeting between bassist Mark Helias and pianist Matthew Shipp evokes nine inspired dialogs from two consequentially compatible jazz musicians, beautifully captured in the warmth of the Park West Studios in Brooklyn.
