This week on The Marketplace of Ideas, Colin Marshall talks to John Rabe, longtime public radio personality and host of KPCC’s Off-Ramp, a weekly examination of Southern California and especially Los Angeles. The show’s interviews and field pieces provide, as Rabe puts it, a “pointillist” aural image of the city and its surrounding half-state, highlighting some of the most interesting people, places, and things there without attempting the futile task of precisely representing the massive amount and constantly changing composition of Southern California culture.

The Marketplace of Ideas airs every Friday morning at 8:00.
