Great country recording

THE SONGS OF BILL MONROE
by: Ricky Skaggs & Friends

Great suggestions already mentioned. Here are a couple more:
T-Bone Burnett / T-Bone Burnett
Old & In The Way 
Willie Murphy & Spider John Koerner / Running, Jumping, Standing

Second the Derailers.

Also the Hacienda Brothers put out great sounding stuff. I have an ultra rare live recording of them called Music for Ranch and Town that absolutely smokes!

And another (I just put on tonight & it sounds great)
Gringo / Combine 

Man, some of this takes me back to my childhood.  Sometimes we would listen to The Grand Old Opry over our old console radio.  My mom loved Hank Williams, The Masters Family(more gospel), The Carter Family, Charlie Pride, Porter Waggoner, Buck Owens and many of the others.  Thank God for streaming services.  I don't have any of this stuff on album or CD.  Was too busy listening to rock and electronics for the last fifty years.
