I received this news via the IDRS email list today:
Sadly, we report that after Friday evening’s dress rehearsal of the Oklahoma City Philharmonic, with Sergiu Comissiona as guest conductor, Mr. Comissiona died in his sleep at his hotel.
Maestro Comissiona worked with Symphony Silicon Valley at the beginning of this season. I had wondered how his health was, and felt that he seemed weary on the podium during rehearsals. But when we got to the performances he was quite the ham; this was our opening weekend in the new California Theatre and we had a movie theme, so a dancer dressed like an usher from the old theatre days brought out a card announcing each work prior to the piece. I thought it a bit gimmicky, but Comissiona went along with it humorously and I was impressed with his playfulness.
