While director of Opera McGill, Wachner premiered "Evangeline Revisited", an opera in two acts based on Henry Wadsworth Longfellow's "Evangeline". Written to commemorate the 250th anniversary of the 1755 Expulsion of the Acadians, the opera features a French libretto by Université de Montréal professor Alexis Nouss and blends multiple musical styles, including jazz, blues, Puccini-esque opera, fugue and cabaret. The role of Evangeline is split between two sopranos: one who represents Longfellow's vision, and one who serves as a contemporary commentator. The opera received its US premiere at New York City Opera's VOX Festival in 2010.
