The Black Keys played the Bank of America Pavilion in Boston over the weekend, and the Boston Globe called the show "a searingly superb 85-minute set." In his review, Jonathan Perry describes the band's style as a "sizzling fusion of hill-country blues and indie-rock attitude." The Boston Herald, too, complimented the show: "In the best of ways, The Black Keys can make a multimillion-dollar venue sound like a dive-bar stage." The video for "Tighten Up" has been nominated for Best Breakthrough Video at MTV's Video Music Awards.

Punch Brothers were featured on the latest episode of NPR's Weekend Edition. Host Jacki Lydon describes their latest release, Antifogmatic, as "10 delectable tunes," and comments that though the band members have their roots in bluegrass, the album is more varied in its sound; she notes that "the band takes bluegrass instrumentation and combines it with elements of classical music and rock 'n roll."

Stephen Sondheim celebrated his 80th birthday in March in a Lincoln Center concert that will be broadcast on PBS this fall. The festivities continue this weekend as Sondheim is the focus of two concerts on the same day, nearly 4,000 miles apart: at the Ravinia Festival Pavilion outside Chicago and at London's Royal Albert Hall for BBC Proms Saturday night. Sondheim is the BBC Radio 3 Composer of the Week.

The Black Keys performed their second and third consecutive sold-out shows in New York City last night, at SummerStage in Central Park and at Terminal 5. The New York Times says: "At their best and starkest, they can make a growling riff feel loose and woozy, tempos fluctuating as if on a column of air." The New York Post says they "made an incredible amount of music for two guys who obviously know size doesn’t matter when it comes to the blues ... [T]he guys were unstoppable."

The 45th annual Cambridge Folk Festival gets under way tonight at Cherry Hinton Hall in Cambridge, England, and three Nonesuch artists are set to take the stage there this weekend: Natalie Merchant headlines Saturday night, Carolina Chocolate Drops perform both Saturday and Sunday, and Rokia Traoré performs on Sunday. BBC Radio 2 will broadcast highlights next Wednesday.

Nonesuch Records is set to release violinist Gidon Kremer’s De Profundis, featuring the Kremerata Baltica chamber orchestra, on September 14. The album’s 12 pieces, selected from Kremer’s performing repertoire, span nearly two centuries, from Schubert to Schnittke—artists who sought to "sustain humans by appealing to their profoundest emotions," says Kremer. De Profundis is available for pre-order in the Nonesuch Store.

Natalie Merchant's tour resumes in the US next week following a stop in the UK for the Cambridge Folk Festival this weekend. Fans on both sides of the Atlantic can now pick up an iTunes Session from Merchant with reimagined original music and cover songs. The Grand Rapids Press gives 3.5 of 4 stars to a recent show, full of "compelling songs, tight musicianship and Merchant's strong vocals."

Emmylou Harris was among the stellar line-up of performers who gathered to celebrate the music of Paul McCartney at the White House early last month as President Obama presented McCartney with the Gershwin Prize for Popular Song from the Library of Congress. The event, also featuring performances from McCartney and Stevie Wonder (the first recipient of the award) among others, will be broadcast on PBS stations tonight.

There's one month to go before the August 31 Nonesuch release of Philip Selway's solo debut album, Familial, now available for pre-order. Selway spoke with Pitchfork about the new project, which it describes as "10 hushed folk songs in the shadowy tradition of Nick Drake. The album is quiet, but there's an unnerving sense of dread that connects the material to his main gig; it's music for a foreboding twilight."

The Black Keys have kicked off their North American tour, offering the home-state crowd in Cleveland their "most superlative-sapping local performance to date," raves the Cleveland Plain Dealer. "Eardrums were ravished. Minds were blown. And when singer-guitarist Auerbach and drummer Patrick Carney finally made their exit, sweat-soaked and utterly spent, it was no small wonder that the downtown skyline was still standing." Pat and Dan's fathers appeared on WKSU radio to offer their unique perspective on the band.
