I was able to see this rap video's debut in Atlanta at the AEA and really loved it. Russ Robert and John Papola are to be commended for a job well done. For the intellectual history behind this rap video see this page. [See updates below]
Update I : On a related note here is an interesting paper titled "Hayek versus Keynes on How the Price Level Ought to Behave" (gated) by George Selgin.
Update II: On another related note, William White says the future of macroeconomics should be shaped by a synthesis of Keynesian economics, Austrian economics, and Minskian economics. I think such a synthesis would point to monetary policy that (1) targeted nominal spending and (2) implemented a robust macroprudential framework. See here for more of White's insights leading up to the crisis.
