These days, country music, which was long ago swallowed into the homogenizing pop culture machine, is like any other element of entertainment media: It lacks decorum, glorifies wealth and is geared toward the basest concerns of the masses. The only thing that distinguishes it is a Southern accent and that boot in your ass. Once upon a time, though, country music had its own identity, one that was far from the artless, soulless corporate goo oozing out of your radios and televisions. It was proud, pastoral, working class and sometimes a little rowdy. Long associated with that kind of country (and the right wing), these days the legendary Merle Haggard seems a bit pained by the country's corrosion. A few years ago, the Okie from Muskogee, who is now in his 70s wrote and sang, "What happened, does anybody know? / What happened, where did America go? / Everything Wal-Mart all the time / No more mom and pop five and dimes." See Haggard, poet of the common man, shun artifice down in Mescalero tonight.
