On November 4, Punch Brothers and Steve Martin will perform together on The Late Show with David Letterman. Additional upcoming highlights include tour dates with the Dave Matthews Band and Dierks Bentley, as well as a special performance alongside T Bone Burnett at the Hardly Strictly Bluegrass Festival. Moreover, Jon Brion, who produced Punch Brothers' new album, Antifogmatic, will play a special opening set at the band’s LA show in October.

Nonesuch Records wishes to congratulate Punch Brothers' Noam Pikelny, who has been named the winner of the first annual Steve Martin Prize for Excellence in Banjo and Bluegrass. "Noam is the extraordinary banjoist for the Punch Brothers," Martin said in announcing the award, "playing not only traditional bluegrass, but classical, rock and jazz oriented music. He is a player of unlimited range and astonishing precision"

There is just one week to go before the release of Steve Reich's Double Sextet and 2x5. Until then, you can listen to the album streaming in its entirety as an NPR First Listen. "Reich's innovations across the decades seem to have been distilled and polished to a sheen not heard in his music before now," says NPR of Double Sextet. "[W]hat makes every new Reich recording an opportunity to uncover new mysteries is his continued willingness, as with the rock idiom of 2x5, to shift gears and change direction. He makes it easy to want to follow him on a wild, joyful ride."

Pat Metheny follows last spring's worldwide Orchestrion Tour with an additional 19 North American performance halls beginning October 1. He has performed shows to sold-out audiences in some of the world’s best-known halls, including two sold-out nights at New York City’s Town Hall. London’s Telegraph calls the show “a triumph,” while the Kansas City Star says, “Metheny’s Orchestrion is nothing short of spectacular ... Endlessly fascinating and visually dazzling.”

With AfroCubism due out in just over a month, National Geographic has an exclusive music preview, streaming the album track "Al vaivén de mi carreta." The album and band are the cover story of the October issue of Songlines. "It's a quite superb coming together of Cuban and Malian traditions to create something that sounds excitingly fresh and new," says writer Nigel Williamson. "There was a genuine creative tension between the tightly structured approach of the Cubans and the looser, more improvisational attitude of the Malians. And it's perhaps this tension that makes it such an exciting album."

"The Comet Song," the new song from Björk, is now available exclusively as a digital download from iTunes.  All the artist and record label proceeds from sales of the track sales will be donated to UNICEF to support their efforts to aid children in Pakistan. Björk wrote and performed "The Comet Song" for the new, animated Finnish children's film Moomins and the Comet Chase.

The Punch Brothers' tour is back in full swing and headed to Austin this Friday. The band has added a new tour date back on their home turf at Brooklyn's Southpaw, October 21, as special guests of Dierks Bentley. The performance marks the closing night of Bentley's four-night, four-venue New York City residency. Fans across the country will be able to hear the show as it airs live on Sirius/XM on both The Highway and Bluegrass Junction channels.

Lonely Avenue, the forthcoming album pairing Ben Folds and Nick Hornby, is featured in Billboard, in which Folds says it was an "instinct to collaborate and make music with people who aren't necessarily musicians" that led to his unique pairing with the English novelist. The Evening Standard says: "They fit beautifully together ... Hornby fans will recognise the tone immediately."

The Black Keys' appearance on NPR's World Cafe airs again today for the show's Best of Summer series. The band hit the road again last night, headlining at the Town Ballroom in Buffalo, New York, with The Whigs supporting. Both bands join up with Kings of Leon for a three-week tour starting in Indianapolis tonight, continuing through September 23, after which The Black Keys launch their own fall headlining tour through November.

Tune in to NPR's Fresh Air today to hear highlights from the Carolina Chocolate Drops appearance on the show from earlier this year, following the release of their album Genuine Negro Jig. It's Country Music Week at Fresh Air, with the show revisiting "interviews with country music's legendary songwriters and performers." The band performs a free outdoor concert in Chattanooga, Tennessee, tonight.

Tune in to The Late Late show with Craig Ferguson to see Sara Watkins perform "Where Will You Be," off her self-titled Nonesuch debut album tonight on CBS. She, Garrison Keillor, and the cast of A Prairie Home Companion bring their Summer Love Tour home to the Minnesota State Fair for a live radio broadcast of the show on Saturday. Watkins promises a song by Harry Nilsson and one by Randy Newman.

Natalie Merchant concludes her summer US tour, featuring music from her album Leave Your Sleep, at the Peace Center in Greenville, South Carolina, tonight. She hits the road again in October for a five-stop tour of the mid-Atlantic states backed by a full orchestra. Glide says the new album shows "once again that Natalie Merchant not only has the chops to be one of the best singer-songwriters of her generation, but rather she is one of the defining ones."
