  ## Reception
  
  The Allmusic review by Thom Jurek awarded the album 4½ stars stating "With this band, he never had to assert himself as a leader because they could instinctively follow his cues. Since that time, he has had to assert himself more and more. And while the music he's writing has every bit of the wonder, awe, and irritation of his earlier work, it has never been played with this virtuosity".
