Drummer Devin Gray teams with Michael Fromanek/b, Dave Ballou/tp and Ellery Eskelin/ts for a rich and open collection of originals. Cool hipness has Gray and Fromaneck link together on “Congruety” with the drummer getting suave on brushes during “What We Learn From Cities.” Lots of quietude on the tender “Quantum Cryuptology” with warm embers from Ballou” whle Eskelin sighs on a b reathy “Trends of Trending” and “Intrepid Travelers.” Gray shows he can dig in well as on the jabbing “Micro Dosage” and the post bopper “The Wire” that slithers like a python. Spaciously swinging.
