I'm not attending the joint string quartet performances by the young Johannes Quartet and the retiring Guarnerius tomorrow night, because I have a rehearsal. But there have been major changes in the program they'll be performing, owing to the unexpected death of the brother of C.J. Chang, violist of the Johannes. Lesley Robertson of the St. Lawrence - big kudos to a real trouper - is subbing for him, and the Mendelssohn Octet and Derek Bremel's Passing Through will be performed as planned. However, the new octet by William Bolcom and Esa-Pekka Salonen's highly anticipated Homunculus will not be played. The Guarnerius will add in a performance of Dvorak's "American" quartet.
Deepest condolences to Mr. Chang and his family over this tragedy; I'm sure he will be in everyone's hearts during the concert.
