Canadian-born violinist and conductor Peter Oundjian will be officially introduced today as the new music director of the Toronto Symphony Orchestra. The TSO has been director-less since Jukka-Pekka Saraste quit in something of a quiet huff in 2001, and in the two years since, the orchestra has struggled with massive deficits, the threat of bankruptcy, and an ongoing dispute between the musicians and orchestra management. Oundjian, who took up conducting after an injury drove him from his place in the Tokyo String Quartet, is widely considered to be a rising star among North American conductors.
