As to the second point, probably not, but how can we say?
As to the first, again, this is not an avant garde vs. mainstream thing. Josh Berman, Keefe Jackson, or Mike Reed are not working in strictly avant garde contexts. Neither is Sylvie Courvoisier, nor Tarbaby or Trio 3, nor Nicole Mitchell, Steve Lehman, Tony Malaby, Angelica Sanchez, Wadada Leo Smith, Dennis Gonzalez, Harris Eisenstadt ... It's a question of accurately representing the landscape of modern jazz. If you like the new Dave Douglas & Uri Cane record, there's nothing that would scare you away from anyone I listed above. There's no reason to ignore what's actually happening.
Shrug. I still don't understand why you believe these guys are making "original music" in a way that Jason Moran is not. Seems like this boils down to "music I like" and "music I don't like".
perhaps because the album featured on NPR is a tribute to Fats Waller?
