says it's from the "Essence Festival Rehearsals 1998"
"jonz" is the only song off brown sugar i can listen to these days from playing that album to death. the bassline, the whole rhythm of the studio version is FIRE.
that's ?uestlove and the soultronics methinks.
*edit, WOW there's a lot of "D'EFR98" tracks on YT. This is brand new to me, WOW. This is D' entering his prime.
