Wilco, The Black Keys, and Amadou & Mariam will be among the bands playing at this year's Lollapalooza, the event's organizers have announced. The lineup for the three-day festival, to be held at Chicago's Grant Park, August 1-3, includes more than 100 artists, including Radiohead, The Raconteurs, Nine Inch Nails, and Kanye West.

"Ry Cooder is probably my guitar hero," Billy Bragg says in a Sunday New York Times Playlist. "The economy of his playing is something to be admired at a time when guitar players tend to think the more notes you play the better you are. My Name Is Buddy is up my street because it's capital-P Political ... There's a lot of love in the songs; they fit well in the tradition. Woody Guthrie's spirit runs through this record very strongly. Cooder plays stuff that we now refer to as Americana, but nobody called it that then. His excursions have been great, but for him to come back to where he began is pretty cool."

This past Sunday, much of the music world converged on the Staples Center in Los Angeles for the 50th Annual Grammy Awards. Nonesuch was well represented there and at the after-party thrown by the Warner Music Group. Here are some shots of the guys from Wilco, The Black Keys, and Punch Brothers, joined by their dates, from the two events.

Wilco's Sky Blue Sky, it's just been announced, is among the nominees for the 2007 Shortlist Music Prize, which recognizes the most creative and adventurous albums of the year. The winner will be announced early next year. Wilco was previously nominated for the Shortlist Prize in 2004 for their last album, A Ghost Is Born.

Wilco's Sky Blue Sky is on the Boston Herald's music critics' list for Best of 2007. The Herald writes that "Jeff Tweedy finds a foil and ace guitarist in Nels Cline and proves what music geeks have said for years: Wilco may be the American band of the decade."

NPR listeners have had their say: Wilco's Sky Blue Sky is one of the year's best CDs. The album, released in May, is still holding sway with listeners, whose votes placed the record in the top five, in the company of Radiohead, Arcade Fire, Feist, and the White Stripes.
