I have, and like, those early Funkadelic albums now, and they're my favorite George Clinton by far. But didn't actually ever hear them back in the day, just knew of their existence. And doubt I would have been into them even if I had heard them back then - it took me 25 years to gravitate to them. The whole Westbound label seemed pretty strange, especially with those bizarro album covers (and I've still never heard those early Ohio Players albums, as I have no use for their later work on Mercury).
I foolishly have sold off that "On The Corner" box twice. It brought me good money, but I should have held onto it and done without something else.
