If you missed the December 12 interview with Eric Christensen, director of The Trips Festival documentary, you can hear it on the KPFA archive any time.
And the four-hour Bob Dylan documentary hosted by Patti Smith, which was broadcast December 19 on DTTW and Sing Out!, is also available on the KPFA archive.
All KPFA programs are archived. Here is a link to the Dead to the World archive.
