You gotta hear this: Podcast recommendation - Cocaine and Rhinestones

"Cocaine and Rhinestones," presented by Tyler Mahan Coe (son of David Alan) is one of the best podcasts I've heard, and certainly the best one devoted to real, country music. It's one of those things I can't recommend highly enough, and the two-parter devoted to Buck Owens/Don Rich is a great place to start.
