James Gadson is one of the greatest drummers of all time.
Perhaps a bit too obsequiously, I call the man Mr Gadson, but then again, he is on records by everyone from Marvin Gaye to Dyke & The Blazers. He's been sampled by Public Enemy, NWA, some of the hardest core rappers out there, so you've definitely heard him play!
Check out his laid back seriously groooved playing on What's Going On or Bill Wither's "Use Me" (below). James -- err--- Mr. Gadson is due all respect and then some. His awesome career is as unique as it is long.
A true living legend, he plays every Monday night at Harvelle's with Kirk Fletcher.
