Funkadelic: Talk About Jesus (Westbound Records, 1971?)
George Clinton's Funkadelic were known for many things, but keenly-felt religious hymning wasn't one of them. Perhaps that's an oversight on all our parts, as they clearly had "it" in them - "it" being a love for the lord as well as a head full of eyeball-scouringly powerful chemical enhancers. Exemplary work from Bernie Worrell on the old joanna to "boot". Much more of this sort of think here.
