BSO Artistic Partner Thomas Adès returns for a concert featuring the world premiere of his own second piano concerto, commissioned by the BSO and composed for Kirill Gerstein, a frequent collaborator. Mr. Adès also leads the orchestra in two Romantic-era scores. Franz Liszt's Mephisto Waltz depicts a scene from Nicolaus Lenau's 1836 poem Faust in which Mephistopheles plays demonically on a fiddle during a wedding. Tchaikovsky's emotionally intense and magnificently orchestrated Fourth Symphony, completed in 1878, represents the culmination of a traumatic period in the composer's life.
