@taxonomy: Have you read the entire thread? The "Country" music to which you refer is not at all what Americana (the underground---not on radio or TV---"Hard"---Traditional---Country) artists (T Bone Burnett, Emmylou Harris, Lucinda Williams, Iris DeMent, Gillian Welch, Buddy & Julie Miller, Jim Lauderdale, Marty Stuart, Rodney Crowell, Steve Earle, etc. etc.) are producing.
Are you saying Robert Plant is making music (his two albums with Alison Krauss) which is "classic rock with an occasional mandolin"? You my friend need to try a little harder if you want to know what is available for your listening pleasure (reading this whole thread would be a good start). You ain’t gonna hear it on commercial Country radio, and shouldn’t expect to. That’s like expecting to hear Rock ’n’ Roll on a jazz station. Just because the music business calls something "Country" doesn’t make it so. As T Bone years ago said: "They’ve learned how to sell Country music to people who don’t like it." It’s called marketing, which is all the music business is now.
Have you seen the movie Ghost World (a great one)? If so, think back to the scene where Steve Buscemi’s character is dragged to a Blues club by his date, and the band Blues Hammer gets up on stage and bludgeons (Blues Hammer is an apropos name ;-) Blues music with their hideous attempt to play it? The Country music you have apparently heard is the Country equivalent of Blues Hammer.
