Steve Reich's 75th birthday celebrations continue with a free concert in Chicago's Pritzker Pavilion at Millennium Park tonight. The concert features performances by Chicago's own eighth blackbird and Third Coast Percussion and an all-Reich program comprising what the Chicago Tribune counts among "some of his finest pieces": Double Sextet, Mallet Quartet, and Music for 18 Musicians. Chicagoist calls it "the most anticipated show of the summer." Catch a video preview here.

Composer Steve Reich's music has recently been celebrated with an all-Reich program at the BBC Proms in London, and more praise from the UK arrived this week, with the announcement that Reich's album Double Sextet / 2x5 is on the shortlist for this year's Gramophone Classical Music Awards in the Contemporary category. In a review of last week's Proms, the Observer reported that Reich "received a rock star's welcome at a late-night concert held to honour his 75th birthday later this year," and according to the Guardian, "Steve Reich gets cooler every year, just as his music gets more relevant."

Björk has revealed the cover of Biophilia, her forthcoming album. Björk’s most interdisciplinary project to date, Biophilia comprises a studio album, an app, a new website, custom-made musical instruments, live shows, and educational workshops. She has collaborated with app developers, scientists, writers, inventors, musicians, and instrument makers to create a unique multimedia exploration of the universe and its physical forces—particularly those where music, nature and technology meet. The Guardian calls "Virus," the latest app component, "an an innovative and important app. But crucially, also a fun one."

The Carolina Chocolate Drops are collaborating on their first theater piece, which will be performed at Chicago's Old Town School of Folk Music this November. Keep a Song in Your Soul: The Black Roots of Vaudeville was commissioned by Old Town and explores songs written and performed by African Americans between 1830 and 1930. The band is working with jazz composer-pianist Reginald R. Robinson and the Old Town School's Reggio "The Hoofer" Laughlin on the production. Bandmember Dom Flemons tells the Willamette Week, “There’s so much stuff that people just don’t know about in terms of music ... we want to reach back and grab that stuff and make it live again.”

The cover art for The Black Keys’ 2010 breakthrough album Brothers, along with its designer, Michael Carney, was praised for its simple power in a New York Times article about a new trend in the music industry to use designs that stand out on digital devices. The band performed a blistering set at San Francisco's Outside Lands Festival this weekend, "dominating the stage with its energetic, classic rock ’n’ roll," according to the SF Examiner.

Steve Reich, who performed at London's Royal Albert Hall earlier this week for the BBC Proms, is the subject of the Guardian's latest Music Weekly podcast. In an extensive audio interview, Reich discusses works from throughout his career, beginning with his latest, WTC 9/11. "This is the first time that the show has featured a contemporary classical composer," says the Guardian, "but Reich's influence on a number of Music Weekly favourites such as Radiohead, Godspeed You! Black Emperor, Brian Eno, Sufjan Stevens and Battles is huge."

Composer Steve Reich comments on his forthcoming Nonesuch Records release, featuring his piece WTC 9/11, performed by Kronos Quartet, and the album cover.

Steve Reich performed at London's Royal Albert Hall last night as part of an all-Reich program with Ensemble Modern for the BBC Proms. The concert is now available online. "There could be no better way of celebrating Steve Reich’s 75th birthday than with a performance of his Music for 18 Musicians," says the Independent in its five-star review, "and the packed hall for this late-night Prom testified to the size and devotion of his fan-club." The Guardian says the concert helped mark Reich's "ongoing acceptance into the pantheon of the greats of the western classical tradition."
