Buena Vista Social Club's leading lady, Omara Portuondo performs an intimate concert for NPR's Tiny Desk Concert series. "Her performance here of two classic boleros was enough to transport us to another time and place," says NPR. "Achingly tender and direct, her Tiny Desk Concert reflects the passion for life she instills in every performance." Portuondo will perform with fellow Buena Vista stars in New York, Chicago, and Los Angeles this summer.

Next week, Adams will lead the LSO in the European premiere of City Noir, which, he writes in the Times, is "an imaginary film score, a musical study in cinematic colours and jazz-inflected energy."

There are just a few days left on The Low Anthem's tour with the Avett Brothers, after which the band will headline its own US tour, beginning in DC. "The Low Anthem isn't the first bunch of indie rockers to experiment with older string-band instruments and echoes of the songs of pre-1940 rural America," says the Washington Post. "But no one has done it better than this Rhode Island trio on its breakthrough album, Oh My God, Charlie Darwin." The A.V. Club talks with front man Ben Knox Miller about the music.

The Carolina Chocolate Drops were on NPR's Fresh Air earlier this week, talking with Terry Gross and performing songs off Genuine Negro Jig. WNYC's Soundcheck names the album among its CD Picks of the Week. The Winnipeg Free Press gives it four stars, citing the "definite feel-good vibe." The Huffington Post reports from the Chicago show that the band "wrapped you in the sheer joy of this music played out loud."

Emmylou Harris will join Dave Matthews and a host of guest performers at Nashville's Ryman Auditorium on May 19 for the Music Saves Mountains  concert, presented by the Natural Resources Defense Council.

Also performing will be two of Harris's frequent touring partners, Patty Griffin and Buddy Miller.
