Artist: Wilco Review: Have Wilco ever come up with a better song than “ImpossibleGermany”? For the first three minutes, it’s a mysterious soft-rockballad with jazzy chords filtered through stoner-country guitarlicks, like some lost outtake from Steely Dan’s Katy Lied.Jeff Tweedy mumbles about isolation in his most beaten-up-by-lifevoice. Then, in the final three minutes, it builds into atwin-guitar epic, with Tweedy in the left speaker reinventingFleetwood Mac circa Bare Trees, and Nels Cline in. Rating: 4 Stars
