Colin Marshall talks to documentary filmmaker Nicholas Sherman, director of Soundtracker: A Portrait of Gordon Hempton. Hempton, one of the world’s best-known field recordists, has dedicated his life to traveling the United States and the world to create “sound portraits” of distinctive places. In Soundtracker, Sherman follows Hempton’s road trip in his 1964 VW bus which becomes a quest to capture the sounds of a train and a songbird together.

Colin Marshall talks to film critic David Sterritt, chairman of the National Society of Film Critics and former longtime critic at the Christian Science Monitor. Sterritt’s books, from titles on Jean-Luc Godard and Alfred Hitchcock to more recent ones on B-movies and even the television sitcom The Honeymooners, reveal cinematic interests that stretch from the avant-garde to the long and widely beloved to the ostensibly (but perhaps not actually) disposable.

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 portrait 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.
