Andris Nelsons leads the American premiere of a new work, Partita co-commissioned by the BSO and the Gewandhaus Orchestra of Leipzig from esteemed German composer Jörg Widmann, whose powerful Trauermarsch for piano and orchestra was performed by Maestro Nelsons and the BSO with Yefim Bronfman in the fall of 2016. To conclude this program, cellist Yo-Yo Ma and BSO principal violist Steven Ansell are spotlighted in Richard Strauss's picaresque tour-de-force Don Quixote, a tone poem whose episodes illustrate scenes from Cervantes' famous novel. Opening these concerts is Mozart's brief, rarely performed Symphony No. 23, written in 1773 when he was just seventeen.
