A student put me on to HBO’s Def Poetry (I don’t need television if my students all watch it). This was apropos Mos Def being a goddamn legend. I did however, via this tip, discover Saul Williams:
Unconscionably good. You can pick up his latest album here. It employs a pricing mechanism not unlike that recently made notable by Radiohead.
UPDATE: From my wife:
Pff. “Pricing mechanism.” You economists are all alike. It’s called “hey, cool, you get to pay nothing or $5.”
