I have, I'm a big fan of Marty's and I've watched his show (mostly online now) pretty extensively. He tends to surround himself with the some of the most talented musicians in Americana, honky tonk, and bluegrass. He does a lot of stuff with Chris Scruggs (grandson of Earl Scruggs) who is an amazing multi instrumentalist and vocalist as well my favorite hometown boy Chuck Mead of BR459 fame who grew up just a few miles from where I live.Marty and the guys are great! Have you ever heard Paul Martin (Bass player) sing a solo? Great voice! I find it hard to believe that these guys, far more talented than what tries to pass for country these days, get zero radio play. Of course we know that "payola" doesn't exist.
Here's Chris & Chuck playing an old Johnny Horton song, Cherokee Boogie with the Superlatives.
