The new album featuring works by Krzysztof Penderecki and those they inspired by Jonny Greenwood itself stemmed from a concert in Poland last fall that paired the composers' works. Tonight, the AUKSO Chamber Orchestra, which performed in the original concert and on the album, will perform the album's music at London's Barbican Hall. "Penderecki's Threnody still has the power to shock," says The Observer, "while Greenwood's Popcorn Superhet Receiver is already a modern classic." Consequence of Sound gives the new album four stars, calling it "one of the most ambitious albums of the year so far"; Greenwood's pieces "fit exquisitely next to the old master’s."

David Byrne, whose album with Caetano Veloso Live at Carnegie Hall was released last week, has unveiled Get It Away, a new soundwork he created while living in A Room for London, a one-bedroom riverboat installation atop the Queen Elizabeth Hall in London, last month.

"I went out during the day and recorded sounds that I thought might be useful and evocative." Watch Get It Away here.

Stephen Sondheim's Sweeney Todd opened at London's Adelphi Theatre last night, a West End transfer of the acclaimed Chichester Festival production, directed by Jonathan Kent. The production, starring Imelda Staunton and Michael Ball, opened to rave reviews, earning five stars from the Guardian, which calls it "a superb achievement," and the Times of London, which calls it "an absolute bleedin' triumph." The Daily Telegraph says Sweeney Todd is "Stephen Sondheim’s best show and one of the greatest musicals of all time." Earlier this month in London, Sondheim was awarded the Critics' Circle Award for Distinguished Services to the Arts.

The Brad Mehldau Trio’s new album, Ode, with 11 previously unreleased songs composed by Mehldau, is out now. The album is "full of seductive melody, and in its blues and bop references and surging swing, it's explicitly jazzy, too," says the Guardian in a four-star review. "It bears a lot of replaying." The Observer calls the new songs "absorbing," noting that "Mehldau is so brilliant at 'recomposing' standards that his remarkable talent as a composer is often overlooked." The Ottawa Citizen says: "A potent combination of deep lyricism, questing creativity and bar-raising virtuosity, Ode consistently provides the frissons that Mehldau fans have come to expect and that lesser pianists wish they could evoke."

Auerbach tells the Chicago Tribune: "There’s something about those old arenas, where it feels larger than life.
