The Timmins Symphony Orchestra has announced its 2011-12 season, under the leadership of music director Matthew Jones. Designed as a celebration of the City of Timmins’ 100th anniversary, the season features a massed performance of Mahler’s Symphony No. 1 (with players recruited from the colleague orchestras across Ontario’s near north) and a landmark season closer May 4 and 5, 2012: the world premiere of Heart of Gold, a new musical by composer Luc Martin and librettist Laureen Kuhl. Heart of Gold outlines the events that led to the founding of Timmins – the Porcupine Gold Rush (which led to the establishment of the Toronto Stock Exchange), the Fire of 1911, and the decision to establish a permanent community in Ontario’s northeast. Over 80 local volunteer actors, singers, dancers and orchestra members will take part. As well, the orchestra will present a three-concert chamber series, featuring the TSO’s professional musicians and friends.
