Chris Thile and Michael Daves kicked off their three-night run of sold-out shows at Rockwood Music Hall in New York City last night, performing songs from their new album, Sleep with One Eye Open, released yesterday. No Depression calls the album "a smartly-paced and well-varied set of tunes, performed with celebratory vigor and and passion for the material." We're happy to announce the winner of the Martin 000X1AE acoustic guitar in the album pre-order contest: Morgan Mecaskey of Cleveland Heights, Ohio. Congratulations!

Steve Reich was the guest of honor at the Barbican in London for Reverberations, a weekend-long music marathon exploring his music and influence, featuring Kronos Quartet in the European premiere of his WTC 9/11. The Daily Telegraph gives Reverberations a perfect five stars, saying that while Reich's "influence has been massive ... it was the innocence and shy ecstasy of Reich’s own music that left the deepest impression." The Times and Evening Standard give the festival four stars. Kronos gives the Scottish premiere of WTC 9/11 this Friday for the weekend's Kronos in Glasgow festival.

The Low Anthem perform songs from their new album, Smart Flesh, on KCRW's Morning Becomes Eclectic in LA this morning, in advance of their show at The Autry tonight. The LA Times calls the album "a gorgeous, inventively arranged set of reverb-rich roots ballads in which the music's frayed edges add emotional weight." LA Weekly says "These four aim for timelessness with a brand of Americana that nods as much to high-energy gospel and gritty blues as it does to rustic, autumnal hues." The split 12" vinyl of The Low Anthem's Daytrotter Sessions, with Iron and Wine on the flip side, is now available for pre-order.

Chris Thile and Michael Daves, whose debut duo album, Sleep with One Eye Open, is due out on Tuesday, have premiered the fourth and final video in a series of performance videos captured live at New York's Rockwood Music Hall: the traditional tune "Rabbit in the Log." Watch it here. "This ain’t your grandparents’ bluegrass hootenanny," says Time Out New York in a preview of the duo's tour kick-off at Rockwood next week.

Randy Newman's Songbook Vol. 2 is out on Nonesuch next week."Newman never sounds more quintessentially Newman than when experienced, as here, alone at the piano," says the Independent four-star review, "with the lyrical intricacies and ironies of his songs dependent on just his laconic delivery and trenchant accompaniment for their effect." Newman appeared on BBC One TV's The One Show, where sand artist Jamie Wardley designed the sand rendering of Newman pictured here.

k.d. lang and the Siss Boom Bang performed two songs from their new album, Sing it Loud, on Jimmy Kimmel Live! earlier this week: "I Confess" and "Sugar Buzz." Watch them here. Also this week, lang appeared on The Monocle Weekly. The BBC says the album is "instantly striking," with songs that are "rich, masterful and seductive." The LA Times, reviewing last weekend's Stagecoach festival, describes lang as "wondrous," and her "performance provided an eminently satisfying conclusion."

Randy Newman's Songbook Vol. 2 is out next week. He sat at the piano to discuss the album and his career on BBC Radio 4's Front Row. The Daily Telegraph gives the album a perfect five stars. "Known for the clever orchestral arrangements on his album work, the stripped-down feel of the Songbook series allows the sharp craftsmanship of Newman’s playful writing to shine through," says the Telegraph. The new album "is an invigorating celebration of the joys of great songwriting and proof of the power of one man and his piano."

James Farm, the collaborative band featuring Joshua Redman, Aaron Parks, Matt Penman, and Eric Harland, released its self-titled Nonesuch debut last week. Now the group has launched a new website, jamesfarmmusic.com, with songs from the new album, photos, a free download, and more on the project. All About Jazz says the album "positions this über-quartet of established and rising stars as a clear force with which to be reckoned." Jazzwise gives it four stars, saying it "draws out a rich melodic seam of group inventiveness." The Revivalist says the band sets "a new bar for themselves and the genre of Jazz as it continues to evolve.” The world tour begins next week.

Today marks the release of Tell My Sister, a three-disc set comprising remastered versions of Kate and Anna McGarrigle's beloved 1976 self-titled debut; its equally praised 1977 follow-up, Dancer with Bruised Knees; and a collection of previously unreleased songs and demos. Rolling Stone gives the new release four-and-a-half stars, calling the debut album "idiosyncratically perfect." The Boston Globe describes it as "a dizzying but exhilarating ride," the demo disc a "real revelation," and the sisters' music "too enchanted, too singular to ever be forgotten." The Philadelphia Daily News gives Tell My Sister an A.

Steve Reich's 75th was celebrated in style at Carnegie Hall Saturday night with an all-Reich concert that included the NY premieres of WTC 9/11, Mallet Quartet, and 2x5 and a performance of Double Sextet. Carnegie Hall "assembled a starry roster of new-music ensembles," says the New York Times, "and the results will be hard to top." NPR says the concert showed that Reich "continues to make innovative music and is still one of the most important and influential voices of our era." The pieces "were individually marvelous," says SPIN, "and collectively provided a terrific summing up of what Reich is all about ... [E]very piece of the evening was a small miracle." The composer and performers head next to London for Reverberations, the Barbican's two-day celebration of Reich's work and influences.

Emmylou Harris celebrated the release of her new album, Hard Bargain, with a special performance of the complete album at NY's Bowery Ballroom last night. She performs "Six White Cadillacs" on the Late Show with David Letterman tonight and will appear on the Today show tomorrow morning. NPR's Fresh Air calls the new album "the most eclectic and loose-fitting album Emmylou Harris has made in a long time," one that "deserves a wider audience." WNYC's Soundcheck names it a Pick of the Week.
