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.
