The busiest man in rock geeks out about gear with the podcaster.

Continuing his forays out of the comedy community (interview Fiona Apple, Jack White, etc.), Marc Maron headed to Dave Grohl’s studio to record his latest podcast. The hour-long discussion centers on the famous Sound City studio (the subject of Grohl’s forthcoming documentary) and how it shaped Grohl’s musical career.

Grohl is knee-deep in promoting his Sound City documentary: his Sound City Players über group will play Park City Live tomorrow (January 18) in conjunction with the Sundance debut of the film. The podcast is available to download now. The Sound City – Reel to Reel soundtrack is absolutely loaded with all-star collaborations and is due out in March.
