Ellen Rosand's Yale Baroque Opera Project, which has brought one revelation after another, arrives on more familiar ground with a production of Cavalli's La Calisto. Performances are on May 4 and 5; if you go on the 4th, you can also catch Yale Opera's Iolanta.... There's an edifying Tumblr devoted to the multimedia production of HPSCHD, coming up at ISSUE Project Room / Eyebeam. Go here for more about the Electric Circus and, even farther out, Cerebrum.... Recommended: Sean Shepherd's opulent new score Tuolumne, after three photographs by Ansel Adams. The Cleveland Orchestra just gave the premiere; the score is online here.... CUNY will present a lecture by the very distinguished critic and author Paul Griffiths on May 10. Music of Rebecca Saunders, whom I write about this week, will be heard alongside him.... Opportunity Music Project supports free music lessons for kids.... I hugely enjoyed the new documentary Elaine Stritch: Shoot Me, which played at the Tribeca Film Festival. At the screening yesterday, her music director, Rob Bowman, indicated that the astounding Ms. Stritch will leave New York tomorrow, after seven decades in the city. We cannot drink to that.
