Great country recording

I'm a big Buddy Miller fan, first encountered him when he was, supposedly, the opening act for Emmylou Harris at Benaroya Hall in Seattle. But the show was really the Buddy and Julie Miller show with Emmylou Harris. One of my all time favorite performances, despite less than ideal acoustics. 

If you don't have his "Cayamo Sessions At Sea" album with an amazing collection of collaborators, it's a must. The sonics of all his recordings are exceptional, as well.

Second the opinion on Cayamo- very nice stuff

Here are a few of my favorite country albums that all sound pretty fantastic too....

Steve Earle - "Guitar Town" 
Willie Nelson - "Willie and Family Live" - Sounds fantastic and a great performance
David Ball - "Thinkin' Problem"
Alison Krauss + Union Station - "New Favorite"

But the winner for performance and sound quality is

Chip Taylor and Carrie Rodriguez - "Live at the Ruhr Triennale" - Stellar performances by Chip, Carrie, Bill Frisell, David Piltch, Greg Leisz and Buddy Miller. I think this was released on CD only and it is not on Spotify or YouTube. I see the CD on Discogs. It's worth a chance if you like Country, Alt-Country, Americana or just want a fantastic sounding recording to show off your system.

Willie Nelson Teatro with Emalou Harris is great. Willie's guitar work is magic. The Stardust Album is always in my rotation. Cornell Hurd live in a fun and the stories, his Fruit Shack Album is good.

Time-Life sold a subscription-format of CDs back in the late 80s-early 90s that covered popular country from around 1950 through 1972. Each CD covered one year. The set does a very fine job of presenting that period in popular country music. I think the CDs can be found quite often on eBay. 

Current country as played on the radio is horrible and should be mostly avoided. That is a true statement extending back for about 15-20 years (other than any artists listed above still recording).
