"In addition to eight duo tracks, Critical Mass includes a solo feature for each player, wherein each showcases a range of techniques. On "Critical Mass 5:15 Gustafsson's include percussive fingering and staccato blowing producing split tones; on "Critical Mass 6:13 Fernández gives a demonstration of prepared piano at its best. However, as good as they are, the individual pieces serve most to highlight the synergy achieved by the pairing. This is amply demonstrated on the closing track, "Critical Mass 5:59, a fluid, high-energy simultaneous improvisation that brings the album to a dramatic and satisfying conclusion."
