Founded by Artistic Director and conductor Josh Grossman in 1998 (a founding AD of the Markham Jazz Festival), the 18-piece TJO performs music by some of the pivotal composers in jazz – writers like Thad Jones, Phil Nimmons, Rob McConnell and more. The orchestra’s repertoire has evolved to include works ranging from classic swing tunes to the leading edge of contemporary jazz, with an emphasis on Canadian composers and arrangers.
