[1][2][3][4] In a review for AllMusic, François Couture described the album as "a magical 75 minutes of relentless improvising, with a constant shift between open-ended sharing and thrust-and-parry dynamics."

He wrote: "Most supergroups don't live up to expectations, but this one delivers all the promises contained within its name.

"[1] The authors of The Penguin Guide to Jazz Recordings called the album "a titanic encounter," and stated: "Parker's group and Brötzmann's seem to face off cross the Victoriaville stage and argue like dissenters at some ancient debate.
