"Shipp lays down beautifully stark and dark toned chords and notes, and Mateen swirls and probes them in a natural and organic way. There is nothing forced about the music, the two work together seamlessly with a common goal and strategy in mind… from fast paced free improvisation to long and low abstractions of melody and form. Both musicians are patient and sympathetic duet partners and they make music that has an open ended muse and graceful poise." – jazzandblues.blogspot
