In a review for AllMusic, Michael G. Nastos wrote: "Incorporating three of the greatest improvisers in the original free jazz movement, the Profound Sound Trio certainly lives up to its name... this triad goes for all-out, rip-snorting energy music based on the post-modern precepts of John Coltrane, Archie Shepp, and even the outer rim of Albert Ayler... the PST deliver on all cylinders through this set of non-stop improvisations that allow all three members to stretch out without overtly exploiting the outer reaches of their instruments... There's a perfect symmetry between the players, solos are meted out judiciously... Amiri Baraka described freedom music as 'a terrible wholeness,' not in the pejorative but to underline the serious nature of African American expressionism, and how it should be taken without prejudice or dismissive whimsy. The Profound Sound Trio make it known to all they are in business to make sure they are heard in perfect clarity, with not a trace of mistaken identity."[1]
Writing for Moment's Notice, Brian Morton commented: "Dunmall's characteristic approach is plain-spoken and artisanal, favoring straightforward narration over harmonic complexity, a hard-forged blacksmith's tone over anything overtly pretty or folkish. Paired with Andrew Cyrille and Henry Grimes, he sounds like a country boy who's just arrived in town but already shown he's the equal of anyone on the block, and with his own moves... The guys seemed to have as good a time as the crowd. Let's hope it’s a regular association."[4]
