Björk's Voltaic release, documenting in music and video her two-year Volta tour, is due out on Nonesuch next week. Now, and all week leading up to the event, NPR.org is offering an Exclusive First Listen to the entire Voltaic album of songs recorded live in studio at the tour's start. "Björk's music is complex, mysterious and full of unpredictable sonic textures," says NPR's Bob Boilen. "The brilliant performances on Voltaic make it clear that Björk isn't just a visionary, but also an artist who inspires those around her to create equal parts music and magic, in an effort to bring her vision to life."

Christina Courtin's self-titled Nonesuch debut is out now. The Huffington Post calls its mix of a multitude of sounds and styles "a wonderful concoction, with intoxicating moody numbers" and "gorgeous lines" of lyrics. The review notes "Courtin's toasty-warm, reassuring vocal," her "lilting, breathy voice" as what "steers her adventures through layers of hypnotic music and production." Time Out New York calls the record "superb" and "beautifully textured," crediting "Courtin’s commanding voice." She talks to New York magazine about discovering that voice as the subject of the magazine's "Breaking" feature.

Wilco helped celebrate Record Store Day this past April with the early DVD release of the concert film Ashes of American Flags in independent retailers across the US. This weekend, the people behind Record Store Day launch Vinyl Saturday, and Wilco's on board again: Nonesuch releases a special limited-edition 7" single featuring the track "You Never Know," off the band's forthcoming release Wilco (the album), paired with the previously unreleased tune "Unlikely Japan" on the B-side. The band is also offering an autographed Gibson Faded SG Special to be given away to one lucky fan.

Voltaic, the multimedia extravaganza in music and video celebrating Björk's two-year world tour following the 2007 release of Volta, is due for release from Nonesuch at the end of the month. Screenings of Voltaic's concert film component are set for cities across the US the week leading up to and around the June 30 release. And now you can catch a sneak peek at the whole project in a video preview at nonesuch.com/media.

Shawn Colvin's new Live album is due out next week. To celebrate, Nonesuch has teamed up with Martin Guitar to offer a brand-new X-Series guitar, signed by Shawn; three runners-up will win a free, signed copy of the CD. All orders of the album in the Nonesuch Store placed by July 21 (including previously placed orders) are registered to win and include, along with the album MP3s, the exclusive bonus download "Another Long One." The Detroit Free Press gives the album four stars, calling it "an intimate, career-spanning solo recording."

The Low Anthem's Nonesuch debut, Oh My God, Charlie Darwin, was released this week. Rolling Stone places it among "the year's best indie records." The Independent calls it "fascinating" and its opening tune "a gorgeous, fragile piece of work." The Guardian concurs, giving the album four stars and stating: "On the beautiful opener, 'Charlie Darwin,' and the startling 'To Ohio, the Low Anthem evoke a hushed, ethereal transcendence similar to the Cowboy Junkies' The Trinity Session. These are magical songs laden with imagery and poignancy." You can hear a live performance of "Ticket Taker" and a chat with the band on the latest New York Times "Music Popcast."

Seya, Oumou Sangare's first album in six years, is out now. Entertainment Weekly gives it an A, citing "grooves limpid enough to dive into" and comparing Sangare to Aretha Franklin, as "a supremely gifted singer who commands R-E-S-P-E-C-T." The Star-Ledger too cites Sangare's "arresting voice ... as strong and lithe as ever," and sees the album as "a series of upbeat, well-produced songs" with melodies that are "something to marvel at."

Nonesuch will release a new recording of the complete Mozart violin concertos by Grammy Award–winning Latvian violinist Gidon Kremer and his Kremerata Baltica orchestra on July 21. Following their performance of the concertos at Lincoln Center’s Mostly Mozart 2006, the New York Times praised Kremer's "ability to make a work, however familiar, entirely his own, dissimilar in most important details from the way other violinists play it, yet fully within both the spirit and letter of the score.” This two-disc set captures their performance of the five concertos at the Salzburg Festival two days later.

The Low Anthem's Nonesuch debut, Oh My God, Charlie Darwin, is out today. The album receives a Paste rating of 90 and is described in the review as "gorgeous chamber folk," another step in "the evolution of folk music ... following the path cleared by Nick Drake and Tim Buckley." Paste concludes: "[T]hese 12 songs are exquisite." The Boston Phoenix hears ties to Tom Waits's Mule Variations in this "excellent" new record, "moving gently among sepia-toned arrangements of pump organs and clarinets and gruff barnyard blues."

Oumou Sangare, the Malian singer/songwriter known as the "Songbird," has released Seya, her first international release in six years. Toronto's Globe and Mail says the album's title, meaning "joy," is certainly reflected in the music, calling it "modern Malian music at its finest: sophisticated, subtle, beautifully produced ... Its cross-rhythms and flowing, hypnotic instrumental lines underpin all she does, and all she does on Seya, whether crooning, chanting, chuckling or singing with majestic power, is excellent."

The Low Anthem's Nonesuch debut, Oh My God, Charlie Darwin, is set for release tomorrow. The album's first track, "Charlie Darwin," opens this week's episode of NPR's All Songs Considered. "If you listen to just one song today," insists the show's host, Bob Boilen, "make it this opening track to the new CD by The Low Anthem. It all starts off with a sound that at times feels Gospel and then at the very same time feels agnostic. Those two ideas seem at odds with one another, but then the title of the record's called Oh My God, Charlie Darwin."

Nonesuch releases Pulitzer Prize–winning composer John Adams’s Doctor Atomic Symphony on July 28, 2009. A purely instrumental work, the piece is drawn from Adams’s opera Doctor Atomic. David Robertson conducts the Saint Louis Symphony Orchestra on this recording. Said the New York Times: "[T]he score invites you to hear the music—driving passages with pounding timpani, quizzically restrained lyrical flights, bursts of skittish fanfares—on its own terms, apart from its dramatic context." Also on the album is Adams’ 2001 piece, Guide to Strange Places.
