BAM is looking to break ground this fall on an intimate black-box performance space behind the main Opera House.

John Adams led the Pittsburgh Symphony Orchestra, of which he is the Composer of the Year, in two concerts this past weekend at Pittsburgh's Heinz Hall. Featured on the programs were Doctor Atomic Symphony, On the Transmigration of Souls, and selections from Nixon in China. The Pittsburgh Post-Gazette says the composer "has penned some of the best music of the last quarter century" and "gave us a reason to be proud again of the splendor that can emerge from 100 orchestral musicians. He is a composer of our time." The Pittsburgh Tribune-Review calls Transmigration "awesome and haunting to experience" and Doctor Atomic Symphony "a masterly new piece."

Joshua Redman marks the release of his latest album, Compass, in his first live performances with the double trio featured on the record, bassists Reuben Rogers and Larry Grenadier and drummers Greg Hutchinson and Brian Blade, tonight and tomorrow at New York City's Highline Ballroom and in Boston and Albany later in the week. The New York Times recommends the concerts, saying that the album's double-trio format leads to "a result that feels rewardingly loose ... the sort of jazz interaction that can only be further clarified by live performance." The Boston Globe calls the ensemble "a fascinating sonic experiment" that both displays its "supple touch" and creates "churning crescendos."

Mandy Patinkin began his ten-day residency at the Duke of Yorks Theatre in London's West End last Thursday. The Independent gives the production four stars, saying this "meaty solo show" features "a programme that reveals not only Patinkin's range of emotional colours but also his technical virtuosity. From the baritonal hinterland of his vocal engine to those trademark high notes, the skirmishes between registers simply dissolve and the sound is as pure as breathing. Numbers that demand leaping nimbleness and difficult tonal coloration ... are despatched with seamless liquidity and utter conviction."
