Buena Vista Social Club’s Lost and Found is due March 23 from World Circuit Records. Coming almost two decades after the release of the original Grammy-winning, self-titled LP, the new album is a collection of previously unreleased tracks—some of which were recorded during the original album’s sessions in Havana and others from the years that followed. The studio tracks on Lost and Found were recorded at the 1996 Egrem studio sessions in Havana and during a period of rich and prolific creativity stretching into the early 2000s. Lost and Found also features live recordings from the world tours of Buena Vista’s legendary veterans. The album is available to pre-order with an instant download of the album track "Macusa."

"It's a scrupulously selected, richly realized collection of songs," writes NPR's Ann Powers. "Though she didn't write most of these songs, Giddens owns them on Tomorrow Is My Turn ... Her voice—mobile, intelligent, ready to talk back to anyone's presumptions—is always at the center here, guiding the story. Let me be the first to say it: Today is Rhiannon Giddens' turn."

Punch Brothers’ T Bone Burnett–produced new album, The Phosphorescent Blues. The album "shows off their eclectic sound," says NPR's Morning Edition. "The album mixes chamber-music intricacy, improvisational flash, lump-in-throat balladry, and a puckish Debussy cover," says the Boston Globe. The Minneapolis Star-Tribune says the new album features "some choral harmonies that are somewhere between the Beach Boys and heaven." The CBC calls the album "triumphant." "Listening to the Punch Brothers is an exercise in wonder," says the Irish Times. "The playing and harmonies are breathtaking. Enjoy." The Herald Scotland calls it "a quite masterly collection from a quintet of virtuosi."

NPR Music looks back on the 50th anniversary of one groundbreaking piece: "It's Gonna Rain is just one example of Reich's broad musical lexicon that over five decades has influenced countless musicians in classical, electronic and even popular music."

Tigran Hamasyan, whose new album, Mockroot, is out now in France and coming soon to the rest of the world, recently sat down with Le Figaro in France to discuss the new album and to perform two songs from it—"Kars" and "Lilac"—as well as the Johnny Green tune "Out of Nowhere." You can watch all three performances here. "It's been several years now that Tigran Hamasyan has stood out in the world jazz scene," says Le Figaro, through translation. "For this prodigy, it is not only his technique that is impressive, but the way in which he literally dives into the notes ... whirling his fingers in a breathtaking ballet."

Rhiannon Giddens is the subject of a feature profile in the New York Times. Her forthcoming solo album, Tomorrow Is My Turn, "is a showcase for Ms. Giddens’s glorious voice, which merges an opera singer’s detail and a deep connection to Southern roots," writes Times music critic Jon Pareles. "She can summon the power of a field holler, Celtic quavers, girlish innocence, bluesy sensuality, gospel exaltation or the pain of slavery. She can sing velvety, long-breathed phrases or rasp and yip like a singer from the backwoods long ago. For all her technical control, her voice is a perpetually soulful marvel." The album's producer, T Bone Burnett, tells Pareles she has “a pretty profound gift ... I’ve been doing this for 50 years, and I haven’t seen anything like it."
