There was more to the LA Phil’s Tristan Project in its original incarnation in 2004, as led by the orchestra’s then-music director Esa-Pekka Salonen. Each in a series of three concerts included one act of Tristan und Isolde, Richard Wagner’s operatic paean to forbidden love, preceded by a symphonic piece reflecting the opera’s pervasive influence on just about everything that came after. The live action onstage was semistaged by the director Peter Sellars, but the thing to keep your eye on was Bill Viola’s monumental video overhead. Though the project had an afterlife in other halls, the fully loaded Tristan Project with non-Wagnerian extras has never been revived, more’s the pity. Even so, the opportunity to catch Viola’s hypnotic imagery and to discover Gustavo Dudamel’s take on Wagner at his most narcotic is a red-letter occasion. (Act One is heard on December 9 and 15; Act Two on December 10 and 16; Act Three on December 11 and 17. Each concert is sold separately at a top price of $232 a pop, or $464 for the series. In January, Dudamel takes the production to the Opéra Bastille in Paris, where it plays in a single evening, top price €190.) —Matthew Gurewitsch
