The festival ended at Ozawa Hall with the Tanglewood Music Center’s orchestra in a program of audacious works, beginning with Gerald Barry’s “Canada,” a puckish piece that appropriates text from the prisoners’ chorus of Beethoven’s “Fidelio” to create a riotous mélange of sputtered words, high-pitched shouted singing and coruscating blasts from the orchestra. The tenor Charles Blandy was the fearless soloist; Nathan Aspinall conducted.
