Kronos Quartet performs the first of four performances over as many nights in Carnegie Hall's Zankel Hall tonight as part of the Hall's season-long Perspectives: Kronos Quartet. Tonight, Kronos and composer Terry Riley celebrate 30 years of collaboration, with an all-Riley program featuring a world premiere, two New York premieres, and selections from Sun Rings and Salome Dances for Peace.

The Magnetic Fields have made their way across North America, back to the East Coast, where they began their Realism tour two months ago. The tour closes with three nights at New York's Town Hall starting tonight. The band heads to Europe next week for a two-week tour there. Spinner reports that the band played "to thunderous applause" earlier this week in Chicago; Chicago Reader notes the "outstanding lineup" on stage and the music's "thoughtful and inventive" arrangements.

Laurie Anderson and Lou Reed will curate Vivid LIVE, a two-week festival at Sydney Opera House celebrating the world’s best contemporary artists and cultural interpreters, from May 27 to June 11. The primary focus of the festival will be on exploration through improvisation and collaboration. “For me," says Anderson, "the point is to present a lot of things that you wouldn’t normally go to but gives people the chance to jump off their street."

Kronos Quartet was credited, in a recent profile in the New York Times, with "reinventing the string quartet as a vehicle of limitless stylistic breadth." This week, Kronos proves yet again how true that is as it concludes its season-long Carnegie Hall Perspectives series, collaborating with numerous artists from around the globe in four concerts on four consecutive nights from Thursday to Sunday in Zankel Hall. Tune in to WNYC's Soundcheck today to hear Kronos and composer Terry Riley discuss the events and perform live.

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.

John Adams returns to the Barbican in London this weekend for John Adams Focus. He introduces a screening of the film Wonders Are Many: The Making of Doctor Atomic, followed by the UK premiere of Doctor Atomic Symphony, with the composer leading the London Symphony Orchestra. 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."

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. The concert aims to raise awareness about mountaintop removal coal mining and its consequences for Appalachia. Also performing will be two of Harris's frequent touring partners, Patty Griffin and Buddy Miller.

To coincide with the Nonesuch release of Natalie Merchant’s new album, Leave Your Sleep, on April 13, Merchant has announced a European tour in May—her first in eight years—including seven previously announced dates in the UK and now an additional seven dates in Brussels, Amsterdam, Cologne, Hamburg, Berlin, Munich, and Paris. The limited-edition, signed print of Merchant available exclusively with Nonesuch Store orders has now been extended to an additional 500 prints. [Update: These, too, are now sold out.]

Adams will conduct the SFS in multiple performances of El Niño starring Dawn Upshaw this December. Also part of the focus on Adams: an SFS performance of Harmonielehre, led by Music Director Michael Tilson Thomas, and an all-Adams chamber music concert featuring members of the orchestra.
