Timothy Andres's music was featured on a number of concert programs in Los Angeles this weekend, including a piece from his debut album, Shy and Mighty, at Beyond Baroque, and Andres himself joining the Los Angeles Chamber Orchestra on piano for the world premiere of his Old Keys and the West Coast premiere of his re-composition of Mozart's "Coronation" Concerto. "What is most original about Andres’ music so far is its extraordinary pianistic character," says the Los Angeles Times review. "He is a superb pianist with a highly evolved rhythmic sense and a quirky sense of humor."

The Black Keys return to NYC for the second of two shows at Madison Square Garden tonight, following their first-ever headlining show at the venue earlier this month, which the AP says "electrified" the place. The band had a homecoming show at The Q in Cleveland Tuesday. "I’ve caught the Black Keys in a variety of settings," says the Cleveland Plain Dealer's John Soeder. "I’ve never known them to put on a bad show. And I’ve never witnessed them put on a better one than they did on this high-stakes occasion." The Chicago Tribune reports from Monday's show at the United Center that the band's sound remains full of "brawny riffs and rolling, tumbling drums that swing hard."

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."

The Low Anthem will support Feist on her US tour this spring, the Canadian singer-songwriter announced today. The band will join Feist for four shows in the Midwest in June, making stops in Minneapolis, Madison, Ann Arbor, and Columbus. Ticket on-sale dates and details are still to come. Today's news follows an unforgettable week of collaborations for The Low Anthem with The Chieftains and a SXSW set with Bruce Springsteen.

The Black Keys take their North American arena tour to Chicago for a performance at the United Center tonight. At Friday's show at Bankers Life Fieldhouse in Indianapolis, "11,000 attendees rallied around Auerbach's flawless and precise solos and Carney's caveman beats," says the Indianapolis Star. Auerbach tells the Chicago Tribune: "There’s something about those old arenas, where it feels larger than life. It’s like walking into a (big-league) baseball or basketball game, it’s on a different level, and I love that.” At the same time, he tells the Cleveland Plain Dealer, "We don't change anything, whether we're playing on a small stage or a big stage."

The Low Anthem joined The Chieftains in a performance of "School Days Over" on The Late Show with David Letterman Tuesday night, in celebration of the legendary Irish band's 50th anniversary. "The perfect way to celebrate their anniversary," says VH1, "the performance was filled with soul and reverence, and if you close your eyes, will take you back to a rolling, misty, fantastical landscape filled with magic." Watch the performance here. The groups perform in concert on NPR Music on Friday and at Carnegie Hall on Saturday, St. Patrick's Day. The Low Anthem plays its own set at SXSW tonight.

The Black Keys' North American arena tour brought the band to NYC last night for a sold-out show at Madison Square Garden, the band's first-ever headlining show at the venue. They head next to Canada for shows in Montreal tonight and Toronto tomorrow. "The Black Keys are rock stars, and their traditional rock sound electrified Madison Square Garden on Monday night," exclaims the AP, which calls the show "exhilarating, bluesy and loud." Rolling Stone says: "[T]he songs from El Camino cast a spell over the packed arena as Auerbach wound their hooks into broad, euphoric payoffs."
