The most acoustic record from his "goodn's" is "Old Corrals and Sagebrush" which has a lot of nice "doghouse bass" work.

Everything he did since "One Jump Ahead of the Devil" is worth owning.

I have had good luck loaning people "Eighteen Inches of Rain" which may be his most accessible effort, at least to the general Country Music public, although one person I loaned it to couldn't get past the "yodeling" on the first song.

"I Outgrew the Wagon" is recorded in Canada and has a nice acoustic guitar player, but most of his work is really straight Country. It just happens to be of superior quality and good taste.
