If you bought a ticket to David Robertson's SFS concerts on May 31, June1, and June 3 expecting to hear Dawn Upshaw singing Britten's Les Illuminations, you may have missed the fact that the program is now this:
Rossini, Overture to L'Italiana in Algeri
Chopin, Piano Concerto No. 2, with Nelson Freire, piano
Dvorak, Symphony No. 7
I caught this before I clicked through to seat designation.
