The Juilliard Bookstore, which is about to move from its present location to a temporary home on West 66th, is holding a 50% off sale on its stock of scores, CDs, and other merchandise. I picked up Ives's Fourth Symphony, Shostakovich's Fourteenth, Copland's Piano Quartet, and various CDs on the col legno and Kairos labels for a whole lot less than I ordinarily would have. Sale ends and store closes on March 24. Thanks, M. G_.
