Toronto Jazz Orchestra

From Their website:

The 18-piece Toronto Jazz Orchestra (TJO) was created in 1998 to perform music by some of the most important composers in jazz – writers like Thad Jones, Bob Brookmeyer, Phil Nimmons, Rob McConnell and more. Over the past 24 years, their repertoire has evolved to include compositions and arrangements ranging from classic swing tunes to the leading edge of contemporary jazz, with an emphasis on Canadian composers and arrangers. The TJO seeks to educate, entertain, and increase the public’s understanding and appreciation of big band jazz.
