Led by Joshua Abrams on guimbri and double bass, the group features tenor saxophonist Ari Brown, electric guitarist Emmett Kelly, keyboardist Ben Boye, harmonium player Lisa Alvarado, and drummers Mikel Avery and Frank Rosaly.

"[10] John Lewis of The Guardian called the album "a compelling Afro-futurist voyage," and wrote: "What holds everything together... is the spectral presence of Africa – with Abrams' goatskin-covered guimbri bouncing around the mix, sharing sonic space with resonator bells, bow harps and thumb pianos.

"[8] Writing for the Chicago Reader, Peter Margasak noted that the power of the group "is in large measure derived from a singular sense of purpose: to lock in on a single chord and with subtle, kaleidoscopic modality cast a spell at the nexus of a hypnotic groove."

"[7] Eric McDowell of The Free Jazz Collective wrote: "Given the niche that Abrams has dug out for NIS in the avant-jazz scene, it's not surprising that at the root of Simultonality's propulsive character lies rhythm, in particular the hypnotizing ostinati that ground Abrams's simple, sturdy compositions... it's the band's collective focus that accounts for the full unstoppable force of the music.

But like thoroughbred stallions that can be born as the result of careful breeding, the final two racks confirm that compositional and performance smarts exist to move the group onto an even higher level.
