The repertoire is as tried and true as it gets, but there’s no missing the effort to attract new audiences by showcasing a less gray, more diverse talent pool. Randall Goosby, who is young, gifted, and Black, is the soloist in Tchaikovsky’s heaven-storming Violin Concerto. The conductor is Dalia Stasevska, who is young, gifted, female, and Finnish. The program concludes with her countryman Jean Sibelius’s bracing Second Symphony. —Matthew Gurewitsch
