I have mentioned those terrific primers on the economy and the banking system that have aired on public radio’s "This American Life." The material is very complicated, but Alex Blumberg and Adam Davidson provide an accessible and often entertaining survey on what's going on. Anyway, Blumberg and Davidson will headline a "This American Life" stage show on April 19th at the Broad Stage in Santa Monica. The hour-long program starts at 6 and is being presented by KCRW and NPR. Tickets went on sale this morning at KCRW.com.
