As The Low Anthem's tour transitions from Europe back to the States next week, Lake Fever Sessions has published three performance videos the group recorded during a stop in Nashville earlier this year: "Ticket Taker," "Charlie Darwin," and "This God Damn House." The band's rich and varied influences, says Lake Fever, "create a stark, though strangely lush at times, canvas for their melodic folk tunes."

Sara Watkins recently stopped by the Rolling Stone offices to perform three songs off her self-titled Nonesuch debut for the "Smoking Section," which praises her "gorgeous voice and killer fiddle." She is joined for the performances by her brother Sean and keyboardist Benmont Tench (of the Heartbreakers), both of whom are featured on the album as well.

Wilco was joined by Feist to sing "You and I" at Monday night's concert at KeySpan Park in Brooklyn and on Tuesday night's performance for the Late Show with David Letterman. Stereogum posts video of the latter and reports: "Jeff [Tweedy] and Feist enjoy a laid back but engaged rapport onstage that matches the dulcet mesh of their voices, one of those rare collaborative dynamics that enhances the song's meaning as much as it raises the song's profile." Billboard says of Monday's concert: "The sight was American rock 'n' roll at its finest, with one of the genre's most powerful live acts at the helm." WFUV's Rita Houston says: "Great show in a great setting on a beautiful night in Coney Island. Magic was all there."

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.

The Nonesuch Journal brought you a brief glimpse of Björk's forthcoming multimedia release, Voltaic, in a video preview of the project earlier this week. Now you can watch the first full-length song performance, "Declare Independence," recorded live in concert in Paris, at nonesuch.com/media. The performance is part of the concert film available in the CD+DVD and deluxe versions of Voltaic, to be released on Nonesuch on June 30, and will be screened in cities across the US in the coming weeks.

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.

The Low Anthem, fresh off a multi-set stop at the Bonnaroo festival this weekend, are in New York City to celebrate the release of their Nonesuch debut, Oh My God, Charlie Darwin, with a performance at the Bowery Ballroom tonight. The Observer Music Monthly gives the album four stars, exclaiming, "it soars, the title track especially"; Paste's Josh Jackson calls it "one of my favorite albums this year." The New York Times writes: "[T]he quieter the music gets ... the more its music inhabits its own otherworldly place, where ghosts and angels hover just out of view."

Amadou & Mariam are set to take Chicago's Park West by storm tonight as they begin the first leg of their summer tour. The Chicago Sun-Times says the couple "front a fiery band that provides a kaleidoscope of music filtering rock, blues, reggae and hip-hop through a Malian sensibility. Her vocals are innocent and welcoming; his blues/rock guitar style is commanding and nimble." The Chicago Tribune declares, "If the duo's vocals are a life-affirming sound that transcends language barriers, [Amadou's] guitar is an instrument of mind-altering eloquence." Time Out Chicago says their new album, Welcome to Mali, "sounds as if it was made, variously, in 1970s flare-wearing New York, in a timeless stretch of desert, and at the kind of party you’d most like to be asked to." Catch the duo on NBC's Late Night with Jimmy Fallon this Monday.

Wilco helped mark national Record Store Day this past Saturday with the limited release of their new concert DVD, Ashes of American Flags, through independent music retailers and on nonesuch.com. Fans in Knoxville got to celebrate up-close with Wilco as the band signed copies of the DVD at the local store The Disc Exchange, video coverage of which was posted online by the Knoxville News. Jeff Tweedy spoke with Spin about Wilco's forthcoming studio album, due out in late spring, described as "a mix of pastoral Americana rock (think 2007's Sky Blue Sky) and experimental studio sounds (2002's Yankee Hotel Foxtrot)."

Allen Toussaint's Nonesuch solo debut, The Bright Mississippi, is set for release on Tuesday, April 21. You can catch a glimpse of the songs, songwriters, and guest artists on the album and take a look behind-the-scenes with Toussaint at piano and producer Joe Henry at the boards in a short video on nonesuch.com/media. The Detroit Free Press gives the album four stars. Rolling Stone says it's "pure Toussaint, emotionally and structurally expansive, yet as keenly done as one of Toussaint's perfectly knotted ties." Dusted magazine says, "It’s quite simply one of the best albums we’ll hear in 2009."

After releasing her debut solo album last week, Sara Watkins took to the road for the start of a monthlong tour in support of the new record. She played with Old Crow Medicine Show through the weekend, and tonight, she performs "Long Hot Summer Days" off the new album on NBC's Late Night with Jimmy Fallon with the album's producer, Led Zeppelin bassist John Paul Jones. Look for support to come from Jimmy's house band, The Roots, as well.
