Michael Tilson Thomas returns to the Toronto Symphony Orchestra podium in a highly anticipated program featuring a work he has conducted to great acclaim throughout his career, Mahler’s tempestuous Fifth Symphony, with its movements of darkness and light, triumphant horn fanfares, and ebullient fugues. Ardent Mahler admirer Alban Berg’s romantic and expressive compilation of seven art songs, written in his youth, opens the program, featuring one of the TSO’s 2023/24 Spotlight Artists, the exquisite Canadian mezzo-soprano Emily D’Angelo.
