It's funny, I would only be able to come up with "herd mentality" argument for people not laughing their asses off at the Lee County Killers, let alone people actually liking them.
Drive By Truckers are perhaps a bit too Southern Rock for me. I need my Southern music with a bit more twang (along the lines of the Two Dollar Pistols) or with more of a Texas influence (early Old 97's, Slobberbone). That being said, Southern Rock Opera is a very good collection. Disk one is very consistent, with some excellent storywriting. Disk 2 is more inconsistent, but has several excellent tracks. The new stuff sounds pretty run of the mill to me...decent material by a band whose enthusiasm and attitude are able to mesmerize a bunch of testosterone driven male fans (and even a handful of female fans).
