Nonesuch Records has signed North Carolina–based trio the Carolina Chocolate Drops, a young string band in the centuries-old Piedmont banjo and fiddle musical tradition. The group’s members—Dom Flemons, Rhiannon Giddens, and Justin Robinson—all trade duties as singers and swap instruments, too. The band, which has toured continuously since its formation in 2005, has several US concert dates this spring before taking a summer sabbatical, during which Giddens is expecting her first child. They will resume touring in the fall; their label debut is scheduled for early 2010.

Audra McDonald returns to the stage in this summer's Shakespeare in the Park production of Twelfth Night. Audra, a four-time Tony winner, is making her Public Theater debut in the role of Olivia, joining a stellar cast that includes Oscar nominee Anne Hathaway, who stars as Viola, and Raúl Esparza, star of the 2007 Broadway revival of Stephen Sondheim's Company. The show, directed by Daniel Sullivan, will run June 10–July 12 at the Delacorte Theater in New York's Central Park.

Youssou N'Dour and global non-profit IntraHealth International have teamed up with Indaba Music to launch a global remix contest, featuring Youssou's song "Wake Up (It’s Africa Calling)," from his most recent Nonesuch release, Rokku mi Rokka (Give and Take). Artists like Duncan Sheik, Nas, and R.E.M.'s Peter Buck have donated remixes of the song to raise funds for the IntraHealth OPEN initiative, which provides health workers in developing countries with the latest open-source software technologies. Now, the same tracks used by those artists are being made available to the global music community on Indaba, an online music collaboration tool, allowing fans to rework the song themselves.

Toumani Diabaté wrapped up his tour with Béla Fleck's Africa Project last week to kick off his own US tour with the Symmetric Orchestra this week in New Jersey and New York City. "The Symmetrics deliver a jubilant polyrhythmic party of percussion, electric guitars," says The Village Voice, "and Diabaté's 21-stringed instrument showering notes like a musical waterfall." Fleck and Diabaté are featured on NPR's Morning Edition; on which Renée Montagne describes, after a performance by Toumani: "I could sit all day and listen to that."

Sara Watkins, whose self-titled solo debut was released on Nonesuch earlier this week, and the album's producer, Led Zeppelin bassist John Paul Jones, are featured in a multimedia look at the album in the Wall Street Journal online. No Depression describes the album as "preternatural" for "its gossamer vocals and heavenly instrumentation," lauding Sara's "seamless interaction with a stellar cast of accompanists" and exclaiming: "From the haunting opening strains of [the album opener], you know you're in the presence of an artist working on a deeper level than your average new grasser."

Bill Frisell has teamed up with bassist Tony Scherr and drummer Rudy Royston for a series of Trio performances taking them outside DC tonight and to Chicago tomorrow. "Few jazz musicians have acquired the stature and respect of guitarist Bill Frisell," says DCist, crediting "his intensely personal sound" and "the range of timbres and colors in [his] palette." The Chicago Tribune says that, for The Best of Bill Frisell, Vol. 1: Folk Songs, the most recent Nonesuch release from this "guitarist extraordinaire ... some of his finest recordings have been assembled." The album "plays like the missing link between avant-folk guitarist John Fahey and jazz legend Miles Davis." Time Out Chicago calls him "the quintessential proponent of true roots music—embodying the ever-diverging genealogy of American music from blues and country through the outer reaches of improv heroics."

After The Low Anthem's performance with Ray LaMontagne at The Egg in Albany, New York, Monday night, the Albany Times Union described the band's music as "spare" and "magical," exuding charm in "a hushed, hypnotic way." The Low Anthem helped celebrate the 25th anniversary of West Virginia public broadcasting's Mountain Stage in a special concert last December, now streaming online. "All of them play various instruments," says the show's host, Larry Groce. "They play very subtle music, very quiet, very thoughtful, very interesting tunes."

The Black Keys' singer/guitarist Dan Auerbach stopped by the studios of New York public radio station WFUV for an episode of Words & Music from Studio A to perform songs from his recent solo release, Keep It Hid, with his uncle James Quine, and discuss the project with the show's host, Russ Borris, who calls the album "a fine piece of work ... marked by warm production and some of the best vocals Auerbach has recorded to date."
