I usually listen to a lot of blues - Albert King, Luther Allison, Muddy Waters, Magic Sam, Robert Johnson, R.L. Burnside, etc., etc. but recently I've been listening to a lot of Paco de Lucia. Talk about a musician. I think his innovations likely changed the art of flamenco guitar forever. This is an old vid but there are tons out there.
