oh yes, that Headhunters "God Make Me Funky" is good stuff...I've heard it on many breakbeat compilations, it's been sampled to death hehe
deep funk is what JB called "super heavy funk"...it's just raw funk, dirty sound, whining wah wah guitars, phat bass, syncopated hard drums and a singer w/ a shredded voice:
Deep Funk - Wikipedia
if you listen to the latest compilations from Otis Redding before he died, he was starting to manage to shred his larynx like JB...he even made a cover of "Papa's got a brand new bag", if only he didn't die so young he sure would have blown us all away.
this one for instance:
Otis Redding Remember Me CD
yes, Black Uhuru, Culture, Lee Scratch Perry, Israel Vibration, I roy, Max Romeo, etc etc

lucky you to have seen JB live!!! I never get bored of watching his bootlegs on a big projection screen w/ my DLP projector...his Olympia 1971 concert is just eye popping.
and if you can take it, there's 2 compilations called "thai funk"....now this, my friend, is just really really deep funk up to the top! many US standards sung in thai, totally priceless
