In the afternoon, another rehearsal for the Jubilee Concert. We did not rehearse Ivan The Terrible because I had told Tcherepnin it was in good shape, and in any case other pieces were in much less satisfactory condition and therefore should have the time devoted to them. Zakharov played the Glazunov Concerto well; I would give him a 4 or even a 5. But the concerto is written in such a way that the pianist has very little opportunity to shine in the first movement (the only one the programme had time for). However, this suits Boryusya's playing. Zelikman is riding high; Polyakin* is playing magnificently. The teaching staff was wheeled out for Glazunov's Cantata (Auer led the orchestra, Gabel was principal double-bass, Ferni-Giraldoni**, disintegrating from decrepitude, was the soprano soloist, and so on). This medley of venerable talents resulted in an atrocious mess, and the unfortunate luminaries were punished with a rehearsal lasting over an hour.
