Smithsonian Rock and Roll with Bill Bentley

Deeper Digs is the companion show to the Rock N Roll Archaeology Podcast. We conduct interviews, go on field trips, and comment on special topics with rockers, writers, academics, artists, photographers, producers, engineers, and more. It all ties in with our very big central theme: Rock N Roll History and how it created a feedback loop with the culture and grew into a global phenomenon. Proud part of Pantheon - the podcast network for music lovers.
