Music festivals often pride themselves on reviving works that, for whatever combination of reasons, have fallen out of the repertory. One important French grand opera of 1859, Herculanum, by Félicien David, got its first recording two years ago and reached the opera stage—for the first time in nearly a century—at Wexford Festival Opera this past October. Reviewers of the recording, including New York Arts contributor Ralph P. Locke, were struck by the melodic richness of the music, the keenly characterized solo roles, and the imaginative use of orchestra and chorus. Reviewers of the Wexford production were more muted, though perhaps the low-budget and curiously updated production had something to do with that. Locke, who is a professor emeritus of musicology at the Eastman School of Music, contributed an essay to the WFO’s program book that gives a sense of this fascinating work. We reprint it here with the festival’s kind permission.
