If yr talkin' late '60s stuff, I would expect the cast of non-Cuscuna-ordained blowhards to include Messrs. Wright and Lowe, as well as people like Byard Lancaster, Marzette Watts, Linda Sharrock, Arthur Doyle et al. The Arista-Freedom series aside, I can't really imagine MC jamming Black Beings and things of that ilk. Do I underestimate? Perhaps, but... I have a lot of reverence for that post-Coltrane NY Fire Music, but I can understand the backlash against it, too.
