When you listen to any of the dozens of records that Perelman and Matthew Shipp have made over the years, you can understand why this communion deserves a box set kind of celebration. And ‘Procedural Language’ is yet another reason to celebrate.

While America and the rest of the world tries to regain its footing, Dan Rosenboom, Billy Mohler and Anthony Fung have already made a full recovery music-wise. ‘Refraction’ is the sweet sound of renewal.

There would be no point in remaking an entire album if it were to be done the same way. That was the challenge before Dan Cavalca and he rose to it by converting the freewheeling, improvised ‘Colors of Red Island’ into the creatively electronic ‘Lights of Red Island.’

‘Mayan Space Station’ is another facet of the multi-dimensional artistry of William Parker. The first listens will surprise, and later listens will uncover that the same man who brought us ‘O’Neal’s Porch’ and ‘I Plan to Stay a Believer: The Inside Songs of Curtis Mayfield’ can absolutely be the brainchild behind these spiritual, loose rock jams.

That blues spirit is alive and well inside Mike Zito and with ‘Resurrection,’ he spreads that healing feeling to anyone within earshot of his music.

Matt Mitchell and Kate Gentile’s “for teens,” “spinal thought” and “peripheral drome” are spare conceptions with rich detail filled in on the fly from the assembled collection of improvisation masters.

“It Starts When We Disappear” is the enthralling opening track from Pat Metheny’s upcoming September 2021 release, ‘Side-Eye NYC (V1.IV).’

Dave Seidel’s ‘Involution’ adds color and texture to minimalism in such an inventive way.

The challenge for listeners to keep up is also central to the thrill of listening to ‘Cool With That’ by the improvised music supergroup East Axis.

“What’s Going On” by bluesman Boo Boo Davis and the ElectroBluesSociety isn’t the Marvin Gaye classic, but it’s liable to move your soul, too.
