The Verbier Festival, where yesterday’s hopefuls meet tomorrow’s stars, takes on the “lyrical scenes” of Tchaikovsky’s Eugene Onegin, a work that has much to say about the transition from callow youth to disillusioned maturity. The Russian conductor Stanislav Kochanovsky, a Verbier Festival regular who was first heard here in 2017 leading this very score, heads an international cast of highly credentialed emerging artists from Russia, Georgia, Ukraine, England, and Ireland. Mira Alkhovik is the naïve, bookish Tatiana, who lives quietly in the country. Anton Beliaev is the preening poseur Onegin, to whom she addresses the inflamed love letter that will change her life. Giorgi Guliashvili is Onegin’s friend Lensky, who dies in a foolish duel neither man has the nerve to abort. Ossian Huskinson is Prince Gremin, the elderly aristocrat who gives the spurned Tatiana a great position in Saint Petersburg, to Onegin’s ultimate regret and her own. After initial doubts, Tchaikovsky embraced the story he initially regarded as sketchy and episodic. But he continued to believe that it would be best served by a performance of great simplicity and sincerity. With those qualities in mind, he entrusted the premiere to students at the Moscow Conservatory. The rest is history.
