Russ Feingold, a Democratic US senator for Wisconsin who's been turning his attention to the more relaxed matters of pop music, posted a video on his website (www.russfeingold.org) last month entitled "Fein Tunes", where he discussed music that interested him, offering a shout-out to fellow Wisconsinite, Bon Iver. A later instalment discussed his fondness for Wilco, in particular for 'Mermaid Avenue' (1998), the album of Woody Guthrie songs they recorded with Billy Bragg. Feingold's timing is good as Wilco's new album is released in June, and already available to stream at their website, tinyurl.com/ppx8nn.
