Paul Krugman has a Nobel Prize in Economics and, besides writing a column for the New York Times, keeps a personal blog, “The Conscience of a Liberal.” He regularly posts music videos in some way relevant to what he’s writing about, and they are always excellent picks.

Today it’s Canada’s Arcade Fire performing “Wake Up” at the Choacella Festival in California.
