Miscellany for the end of summer

The Park Avenue Armory is inaugurating a recital series in its newly renovated Board of Officers Room. The first performer (Sept. 29, Oct. 1) is none other than Christian Gerhaher, one of the supreme Lieder singers of the day. In late October, Anton Batagov will play Feldman's Triadic Memories.... The Spektral Quartet is raising funds for a new-music ringtone project (silly video alert)... A stylish new look for NewMusicBox.... The admirable Sonnambula consort returns to St. Luke's on Oct. 2, with "masterworks of the English Renaissance."... This Thursday, the French Institute / Alliance Française in New York presents a collaboration between the artist Xavier Veilhan and the electronic composer Eliane Radigue.... On Sunday, Tim Rutherford-Johnson curates a concert of Some Recent Silences at Kings Place in London.... The fearless Bay Area pianist Sarah Cahill has a new disc called A Sweeter Music, on an anti-war theme. There's a release party in Berkeley on Sept. 22. This week Sarah will also be performing at San Quentin, as part of the prison's arts program; she will be playing works composed by Henry Cowell while he was an inmate.... Another record worth noting: Bella Ciao, a compelling fantasia on ancient Roman Jewish melodies by the hard-to-describe Brooklyn-based ensemble Barbez. They present the record tomorrow at LPR, with Yotam Haber joining in.... Zerbinetta, the mysterious author of the essential opera blog Likely Impossibilities, has revealed herself as the musicologist Micaela Baranello.... Alan Rusbridger's marvelous book Play It Again is now out in the US. The piano-playing, empire-shaking author appears at the New York Public Library on Sept. 25.
