The BSO’s Opening Night concert begins with a benediction by Leonard Bernstein, a setting in Hebrew for baritone that was the composer’s last work with orchestra; baritone Jack Canfield makes his BSO debut. Bernstein’s Symphony No. 2, Age of Anxiety, comes from early in his career: he was piano soloist in the BSO’s world premiere performance of this jazz-inflected work inspired by a poem by W.H. Auden. In its orchestral finesse and raw power, Igor Stravinsky’s revolutionary 1913 ballet score The Rite of Spring still astonishes after more than 100 years.
