I'm a big alt-country/Americana fan, but have never been as gaga over Wilco as most of my peers. Still, I have tons of respect for Jeff Tweedy's sense of creative adventure. Which is why it's a shame that Tweedy's name is (conspicuously) missing from the rotating cast of Golden Smog collaborators on the Jayhawks-Soul Asylum "supergroup's" utterly dispensable new "mini-album," Blood on the Slacks. Love the title, but that's about all I love. Included are karaoke-caliber renditions of Bowie and Dinosaur Jr.; it's as though these guys grabbed a case of beer, headed into the studio for a night, and hatched a scheme to bang out a half-dozen mediocre originals and cash in on the fact that most fans associate the band with Tweedy. Just a tired, slight effort, boys. The album should come with a money-back guarantee.
