I was a light listening country music boy in Kemah growing up. I loved SRV Rush, Maiden Triumph My parents always listened to old school country. My wife and I started watching this documentary series. And I'm a changed man. This series made me " see the light". This is a must watch. From The Carters to Garth. I'm youtubing muleskinner blues from Dolly Parton. You gotta watch this.
You're a bit late to the party, but yes indeed it's a great documentary. I've yet to see a "bad" Ken Burns doc.
