Punch Brothers stopped by NPR to give a Tiny Desk Concert. The concert opens with a special surprise for Thile, who happened to be celebrating a birthday that day, followed by a performance of four songs from their new album, The Phosphorescent Blues. Thile, "along with this versatile and talented group, rocked our world," says host Bob Boilen. "Punch Brothers mixes bluegrass, pop and classical music. It's a tough combination to imagine, and an even harder one to make work, but this band ... makes the unimaginable contagious and fun. They push boundaries and make music like no one else." Watch the Tiny Desk Concert here.

Buena Vista Social Club's Lost and Found, a collection of previously unreleased tracks, is due out next week. But you don't need to wait till then to hear it: the album is streaming in full all this week as an NPR First Listen at npr.org. "It was nearly 20 years ago, back in 1997, that the Buena Vista Social Club became an improbable worldwide sensation: a group of mainly elderly (and some younger) Cuban musicians, performing traditional son music for an album produced by Ry Cooder," writes NPR's Anastasia Tsioulcas. "If it turns out that this is the year we do say a final goodbye to the Buena Vista collective, Lost and Found provides a gorgeous reminder of what made it so famous to begin with — and what we'll all be missing."

The Nonesuch Records CD/DVD release of Louis Andriessen's opera La Commedia has won the Caecilia Prize by the association of Belgium's classical music press. The film opera, a collaboration with director Hal Hartley, is based on Dante’s Divine Comedy, with additional texts from the 16th-century German theologian Sebastian Brant, the 17th-century Dutch dramatist Joost van den Vondel, and the Old Testament’s "Song of Songs." The recording is a finalist in the 2015 International Opera Awards; the winners will be announced on April 26.

Composer Nico Muhly was the guest on NPR's On Point with Tom Ashbrook. His in-depth conversation with Ashbrook touches on a number of aspects of his work, not least his first large-scale opera, Two Boys.

You can listen to the On Point interview here.

Singer, songwriter, and multi-instrumentalist Olivia Chaney makes her album debut with The Longest River, available April 28 on Nonesuch Records. On the album, Chaney balances her original compositions with a selection of covers she has newly arranged that illustrate the broad sweep of her taste, from jazz to Purcell to folk. "Her voice holds the purity, tension, dignity and sorrow of a heritage full of songs about lost love and cruel fate," says the New York Times. "Ms. Chaney is thoroughly grounded in the past, from medieval music to [Joni] Mitchell. But in her quiet way, she’s radical." The Longest River is available to pre-order with an instant download of the album tracks "Imperfections" and "The King's Horses."

Record Store Day, the annual celebration of independent record stores, is set to take place on Saturday, April 18, and included among the special limited-edition releases on that day are vinyl recordings from Robert Plant, Steve Reich, and Buena Vista Social Club.
