Luther Thomas - Funky Donkey - (Creative Consciousness)
Kind of reminds me of an Afro-rock LP in some ways, at least on the title track, and presages some of James White's work with the Contortions in Downtown NY a few years later. Guitarist Marvin Horne is awesome.
The Solidarity Unit - Red, Black & Green - (Universal Justice)
a little freer than Nation Time, but still the right vibe, especially the stuff with guitarist Richard Martin.
Steve Reid - pretty much all of the Mustevic LPs reissued by Universal Sound, but I bet you'd really dig the Master Brotherhood stuff.
Hans Dulfer & Ritmo-Natural - Candy Clouds, El Saxofon, The Morning After The Third - (Catfish/EMI)
Series of great Afro-Latin Dutch free jazz LPs put out in the early 1970s and reissued on a Hans Dulfer box on EMI. You get a lot of dross with the box, but the early stuff is priceless.
Robin Kenyatta - The Free State Band - (America)
Byard Lancaster - Funny Funky Rib Grib - (Palm)
Related vibe across these two, both including Lafayette Afro-Rock band members Keino Speller (RIP) and Francois Nyombo.
Emergency - Homage to Peace - (America)
Okay, a little more free, but definitely an important cross-national document of early 1970s Afro-free-spiritual jazz, featuring a plugged-in and wily Boulou Ferre!
