Because you're, like, an uncultured philistine? Figures it would take a Southerner to lecture a Canadian on good music. Anyway, both Chairs Missing and Pink Flag are totally excellent in the same vein, though much more loud, abrasive, and punkier. On a good day, Pink Flag may be my favorite punk album.
On topic: the greatest and most influential American band of the '60s (ask Tom Petty and R.E.M. and Wilco and any guitarist who's done the jingle-jangle). The only band to make a #1 hit out of quoting Ecclaisteses (sic, sorry forgot exact spelling). To everything, turn, turn, turn..... "Transcendent" is I believe the proper adjective.
Cheers to Roger McGuinn and Gene Clarke and Chris Hillman and Gram Parsons. I may have it even my heart to say hello that living walrus David Crosby, just for being for a short time in tbe one good band that fat old crackhead's ever been in.
