A bit of a lull this week with the COC fall season over and Yaksmas festivities still, mercifully, some time away.  Still there are a couple of events of note.  Simone Osborne is singing with the TSO at Roy Thomson Hall on Thursday and Saturday in a program of Mahler, Dvoràk, Charpentier and Strauss.  There’s also the fall production from the Glenn Gould School.  It’s a double bill of Xavier Montsalvatge’s Puss in Boots and Luciano Berio’s Folk Songs.  Friday and Saturday at 7.30pm in Mazzoleni Hall.
