The band and fellow guests Renée Fleming, Aoife O'Donovan, and Heather Masse join Keillor and crew live at New York's Town Hall, where Punch Brothers headline later this month. Punch Brothers are featured in the latest installment of the A.V. Club's A.V. Undercover, performing The Cars' "Just What I Needed." Watch it here.

Amadou & Mariam's new album, Folila, is due out in the US on April 10. The album's opening track, "Dougou Badia," featuring Santigold, premiered on Pitchfork earlier this year. Today, Pitchfork has premiered the video for another album track, "Wily Kataso," featuring another stellar collaboration, this time with TV on the Radio's Kyp Malone and Tunde Adebimpe. Watch the video, directed by Jennifer DeLia, here.

Following yesterday's video featuring the title track to Dr. John's forthcoming album, Locked Down, comes a second teaser video with a clip from the track "Revolution" and more footage from inside producer Dan Auerbach's Nashville studio. Watch it here. A third album track, "Big Shot," has been named NPR's Song of the Day. "Auerbach makes 71-year-old Mac Rebennack sound fresh and intimate by connecting him to his vital musical past," says NPR. Dr. John "proves that now, as always, he's the ruler of American roots music."

Release day for Dr. John's new album, Locked Down, is less than two weeks away, April 3. Now you can catch a look inside the studio as Dr. John and producer Dan Auerbach of The Black Keys laid down the album's title track in a new video here. Then head to the Brooklyn Academy of Music's website, bam.org, where the track is streaming in full. Dr. John and Auerbach will premiere music from the album at BAM as part of a three-weekend residency there titled Dr. John: Insides Out, which starts next week.

David Byrne, whose album with Caetano Veloso Live at Carnegie Hall was released last week, has unveiled Get It Away, a new soundwork he created while living in A Room for London, a one-bedroom riverboat installation atop the Queen Elizabeth Hall in London, last month. "I brought along some field recording gear to use while I was staying in the lovely pod/room/boat," Byrne explains. "I went out during the day and recorded sounds that I thought might be useful and evocative." Watch Get It Away here.

Carolina Chocolate Drops, whose new album, Leaving Eden, was release on vinyl yesterday, are featured in a new piece on PBS Newshour's Art Beat that examines the roots of their music. Watch the piece here along with a recent performance at the Library of Congress in Washington, DC. Carolina Chocolate Drops "push an appreciation of home grown songs into brand new territory," explains The Morton Report. "It's not unlike jazz musicians who take popular music into the stratosphere. Carolina Chocolate Drops have essentially erased the rulebook and allowed freedom to become their watchword."

Punch Brothers' new album, Who's Feeling Young Now?, is now available on vinyl. The LP comes on two discs of 140-gram, audiophile-quality vinyl and includes four additional Punch Brothers–penned tunes available exclusively on the vinyl album. To celebrate the CD's release last month, Punch Brothers gave a special invitation-only record-release show at Rockwood Music Hall in New York City; watch three songs from the set here: "Movement and Location," "Clara," and "Who's Feeling Young Now?"

The Low Anthem, having performed on The Late Show with David Letterman with The Chieftains earlier this week, continued a week of stellar collaborations when it joined Bruce Springsteen, members of Arcade Fire, Tom Morello, Alejandro Escovedo, and others on stage for SXSW at The Moody Theater in Austin, Texas, last night for a powerful and moving rendition of Woody Guthrie's classic tune "This Land Is Your Land." Backstreets was there and captured the unforgettable finale; watch it here.

The Low Anthem joined The Chieftains in a performance of "School Days Over" on The Late Show with David Letterman Tuesday night, in celebration of the legendary Irish band's 50th anniversary. "The perfect way to celebrate their anniversary," says VH1, "the performance was filled with soul and reverence, and if you close your eyes, will take you back to a rolling, misty, fantastical landscape filled with magic." Watch the performance here. The groups perform in concert on NPR Music on Friday and at Carnegie Hall on Saturday, St. Patrick's Day. The Low Anthem plays its own set at SXSW tonight.

Punch Brothers celebrated the release of their new album last month with a special show at NYC's Rockwood Music Hall. Their performance of the song "Movement and Location" from that night has premiered in a video on The New Yorker's site; watch it here. Salon's Seth Mnookin calls the song "a propulsive masterpiece that sets the tone, both musically and thematically, for what’s to come" on the album. "Punch Brothers have achieved a kind of mind-meld that’s only possible when preternaturally talented musicians spend hours pushing themselves, and each other, to explore their passion and creativity." 

Punch Brothers are currently on tour in North America and has made its way to California for shows at The Fillmore in San Francisco tonight and El Rey Theatre in Los Angeles Saturday. The band has "further refined its sound on its latest album," Who's Feeling Young Now?, writes the Los Angeles Times. Its "rich and evocative tracks capture a white-hot musical mind coming into his own and collaborating with stellar peers." Last month, following the release of the new album, the band stopped by the studios of NYC public radio station WFUV to perform a few songs off the record. Watch them here.

Björk closed out her month-long, ten-show Biophilia NYC residency last night at Roseland Ballroom. The residency also included shows at the New York Hall of Science, which collaborated with Björk on a Biophilia education series on the scientific concepts at the core of the album. One such concept is DNA, in the song "Hollow," the video for which has premiered on NPR's All Songs Considered. "It takes an artist like Björk to turn the complex process of DNA replication and transcription into something as simple and beautiful as a pop song," says NPR. "For the video of her song 'Hollow,' Björk has collaborated with biomedical animator Drew Berry to create a partly-scientific representation of the haunting song." Watch it here.
