The record I referenced is "A Portrait of Patsy Cline". I have two copies, both mono for some reason. I have one I bought new, has been played on my little Truetone kiddie player a million times and is beginning to show its age. The one I played today is a copy I got at an auction and is in vastly better condition. This record was introduced after her death, and includes some of her favorite covers she recorded. This recording was produced by Owen Bradley and featured the Jordainaires on background vocals. The heavy bass you spoke about was pretty much a Patsy Cline tradition on her Decca sides.
She gained her greatest fame and success with Owen Bradley and the Nashville sound. She tolerated the genre, favoring the barroom ballad type of music. "It pays the bills" was pretty much her attitude. Owen Bradley deserves credit for taming the "bawdy girl" she and her BFF Dottie West were known to be. Bradley toned her down, slowed her down, added an orchestra, gave her "higher class" material. Harlan Howard, Cindy Walker, Hank Cochran provided much of her material, but so did Russ Morgan and Irving Berlin.....

Life can be tough. It can be even tougher if you're stupid.....
