Listen to the concert preview. The Czech conductor Jakub Hrůša, making his BSO debut, is joined by acclaimed German violinist Frank Peter Zimmermann for Béla Bartók's scintillating Violin Concerto No. 2, a 1938 work strongly influenced by Central European folk music. The other three works on the program are based on Slavic myth and legend. Smetana's Šárka, a tone poem from his large cycle Má Vlast ("My Country"), is named for a legendary Czech maiden warrior and illustrates an episode from her life. Mussorgsky's famously scary Night on Bald Mountain (depicted in Disney's Fantasia) seems to have originated in plans for an unrealized opera on the subject of a witches' sabbath, in part inspired by the great Russian writer Nikolai Gogol. Based on a Gogol novella, Janáček's 1918 orchestral rhapsody Taras Bulba is one of his most familiar works-but has never been performed by the BSO.
