JUNE 10, 11, 13, 17 & 18 The Toronto Symphony Orchestra presents a mini homage to Richard Strauss and Béla Bartók featuring super soprano Measha Brueggergosman. Measha Sings Strauss has the Canadian singer performing the composer’s final work, Four Last Songs. Bartók’s orchestral Concerto for Orchestra and the energetic Divertimento for Strings round out the program. On the second ticket, pianist Emanuel Ax takes on two contrasting works: the young Strauss’s playful Burleske followed by Concerto for Two Pianos and Percussion by the more mature Bartók. Roy Thomson Hall, $29 to $132; call 416-593-4828 for tickets and times.
