Lahav Shani conducts Tchaikovsky’s Pathétique, a symphony that the composer premiered less than a week before his death and was later nicknamed for the passion and suffering it expresses. Daniil Trifonov takes the spotlight in former CSO Mead Composer-in-Residence Mason Bates’ Piano Concerto, a journey through three stylistic sound worlds, from Renaissance dance music to Romantic-era brooding to a contemporary finale imbued with strains of jazz and minimalism.
