JANUARY 11 TO 22 The Toronto Symphony Orchestra continues its 90th season by commemorating an even older anniversary—that of Wolfgang Amadeus Mozart’s birth. The ensemble’s annual series of Mozart programming this year highlights two of the composer’s late-period masterworks—his Jupiter Symphony and Requiem—in separate concerts, along with other exemplary pieces and even a “Mozart’s Magnificent Voyage” show for young listeners. Audiences at the January 18, 19 and 22 performances of Requiem are in for an additional treat, as teenage prodigy Jan Lisiecki sits in with the orchestra for Mozart’s Piano Concerto no. 20. Roy Thomson Hall (January 22 at George Weston Recital Hall), $20 to $145; call 416-598-3375 or visit here for showtimes and to buy.
