Civil War Talk Radio is an online author interview forum like no other. Each program is approximately an hour in length and host Professor (and ex-lawyer) Gerald Prokopowicz for the most part asks questions that deep readers would appreciate.
I was finally able to catch the Dimitri Rotov program, which was a very enjoyable encapsulation of Dimitri's views. If you really want to know the backstory of Dimitri's unique viewpoint you can either go to his blog and read every post in his archives (like I did) or listen to this program for the Cliff's Notes version. Actually, I would highly recommend doing both!
While you're at it, take a look at the CW Talk Radio archive of programs. You'll find an excellent range of authors from famous to relatively obscure with the entire spectrum of Civil War studies present.
