Steve Reich, Nonesuch Records, and Indaba Music have launched a search for collaborators to remix the third movement of Reich's new piece 2x5, which Gramophone recently described as his "smartest, most sonically nourishing record for years." For four weeks beginning today, remixers can visit Indaba to create their own version of the movement. From November 9 to 23, fans and a panel of judges, including Reich, will review the submissions. Indaba will announce the jury’s choices on December 7, as well as the public’s top ten.

Punch Brothers are back in California, headlining at LA's El Rey Theater with Jon Brion, the producer of their album Antifogmatic, opening. LAist spoke with fiddler Gabe Witcher and says: "Punch Brothers' music is the sound of synapses firing. The band's mix of unpredictability and virtuosity means there's always something new to uncover in their original pieces." Mother Jones spoke with Chris Thile and says: "What the Punch Brothers are doing musically blows the pants off most of their contemporaries."

AfroCubism is out in the UK today on World Circuit; it's out in North America November 2 on Nonesuch.

The Observer calls it "A delight." The Financial Times gives AfroCubism four stars as well; MusicOMH gives it five stars, citing the "wonderful results."

Rhys Chatham made his Nonesuch debut last month with the release of A Crimson Grail, featuring the 200-guitar version recorded at the Lincoln Center Out of Doors Festival. The New York Times says: "It might justly be considered 'music to pray to.’” Now you can experience that music through a short film set to music from the album, shot on rolls of expired, unexposed Kodachrome Super 8mm film.

Wanda Jackson, whose new Jack White-produced album, The Party Ain't Over, in January 25, performs outside Boston tonight. The Boston Globe quotes Rosanne Cash, who described Jackson "as the prototype, the first female rock star," adding that "Jackson is still kicking out the jams." She performs at the Knitting Factory in Brooklyn on Friday, leading The New Yorker to note "her growly vocals, remarkable energy, and boundless good humor." Jackson spoke with Y'all Wire at last month's Americana Honors & Awards for an interview you can watch here.

De Profundis, the new album from Gidon Kremer and Kremerata Baltica, receives five stars from Audiophile Audition. It's a program "of such sheer delight and exquisite beauty that I felt emotionally ravished when it was over," raves the reviewer. "One of the best collections of its kind that I have ever heard." The album is a Pick of the Week on WNYC's Soundcheck and CD of the Week from KBAQ, which says the music creates "a deep feeling of hope."

The Black Keys have been on a roll on their sold-out headlining US tour, which concludes this weekend. At this week's stop in Portland, The Oregonian says, "the whole show rocked." The crowd at Sunday's show in Vancouver "couldn't have asked for more," says the Vancouver Sun. "The Keys were unrelenting, sweaty and wild right from the very beginning ... Mind-blowing stuff." Following Saturday night's Seattle set, Seattle Weekly says the songs off their new album, Brothers, "were sensual and shit-kicking all at once."

Steve Reich's new album features Double Sextet and 2x5 performed by eighth blackbird and Bang on a Can, respectively. The Wall Street Journal calls Double Sextet "irresistible," saying that while Reich had "already won a place in music history ... [his] appeal to successive generations of performers is equally assured." The Philadelphia Inquirer gives the album an A, calling it "fascinating ... And yeah, it's really rocking!" Gramophone calls 2x5 "Steve Reich’s smartest, most sonically nourishing recording for years ... like an exploding diagram of the inner mechanics of a rock band playing at full tilt."
