I will second Ablert's endrosement. I bought this when it originally came out and it was great. Although 2/3rds of my collection is rock, about 15% is country. The final Bob Wills sessions have great players and is highly recommended to any fan of Western Swing. You might be surprised. But to answer the initial question I would look for sealed country vinyl from the 60's. You can find stuff by Buck Owens, Merle Haggard and others in sealed condition on the auction site.
