Led by its music director, Alexander Mickelthwate, this ensemble offers an immersion in living composers from Canada, including R. Murray Schafer's Symphony No. 1; Derek Charke's "13 Inuit Throat Song Games," featuring the vocalist Tanya Tagaq; and Vincent Ho's "The Shaman," a concerto for percussion and orchestra with the redoubtable Evelyn Glennie as soloist.
