Long running radio show out of Mtl on ckut. Bringin the funk and oldschool hip hop for fifteen plus years. Over 500archived shows where you can skip tracks search etc... they also have a stream on itunes shoutcast and tunein. I would higly recomend it as you will find a lot of rare funk that has never been reissued.
Anyways, of the top of my head right now:
Rufus Thomas
Gil scott heron
fatback band
curtis mayfield
ill be back later with more
