Anything or maybe everything released by Wadada Leo Smith this century. The releases on TUM alone stand up as a truly remarkable body of work.
Definitely agree about the Matana Roberts trilogy.
Then there's releases by what I like to think of as the Chicago scene - Josh Berman, Jason Stein, Jason Adasiewicsz, Mike Reed, Jason Roebke, Nicole Mitchell, Tomeka Reid, Jaimie Branch, Makaya McCraven (not the same scene? but same city). Tim Daisy
Rob Mazurek's small group and large ensemble recordings
Irreversible Entanglements and Keir Neuringer's intense solo record
And I haven't even got to nearer home and Europe yet.
Too many!
And Threadgill on Pi, just take your pick of them
