Found some interesting staff off the web and would like to share:
Introduction from EconStories at youtube:
On October 25th, an audience of financial managers and CEOs, politicians, central bankers and nobel prize winning economists at The Economist Magazine's Buttonwood Gathering were treated to an unusual experience: a live rap battle between John Maynard Keynes and F. A. Hayek.
Following a presentation by Nassim Taleb, the lights went down in the auditorium and Fear the Boom and Bust blasted onto the screen. This video picks up at the end of that special presentation, where Keynes and Hayek stepped onto the stage to give a preview of the next EconStories music video.
In the final new video, which will be completed in the months ahead, expect many more lyrics and an all new beat.
Lastly, Russ Roberts and John Papola took the stage with John Micklethwait, editor-in-chief of The Economist for a brief Q&A about the origins of FTBB and the resurgence of Hayek in the global debate over the economy.

In case you missed the earlier rap mentioned in this rap, here is a re-run:
