Mezzo-soprano Elīna Garanča and tenor Roberto Alagna reunite in the title roles of Saint-Saëns’s biblical epic Samson et Dalila. Darko Tresnjak, who won a Tony Award for Best Direction of a Musical in 2014 for A Gentleman’s Guide to Love & Murder, makes his Met debut directing a vivid, seductive staging, featuring a monumental setting for the last-act Temple of Dagon, where the hero crushes his Philistine enemies. Sir Mark Elder conducts the first new Met production of the work in 20 years.
