Southeastern Louisiana University’s Opera/Music Theatre Workshop will present the world premiere of “Evangeline” by American composer Gwyneth Walker at 2 p.m. Thursday, April 2, in Pottle Music Annex Recital Hall on campus.

The performance, which is free, is based on the poem by Henry Wadsworth Longfellow and will last under an hour. The music is all newly composed, said Director of Opera Workshop Charles Effler. The words are those of the Longfellow poem as adapted by Walker.

“Dr. Walker was in Baton Rouge for a composer’s residency in March 2014 and visited the town of St. Martinville,” Effler says. “While there, she saw the famous Evangeline Oak and was introduced to the legend. It captivated her imagination immediately.”

Opera Workshop welcomes back guest stage director Rachel M. Harris for this production. Harris has directed several Opera Workshop productions including “La Périchole,” “Fairy Tales: Hansel & Gretel and Cendrillon,” “The Pirates of Penzance,” “Street Scene,” “Die Fledermaus,” and “The Marriage of Figaro.” She also directed Opera Workshop’s recent concert of opera scenes and arias, “Opera by the Slice.”

The performance is sponsored by Opera Workshop, the Southeastern Lyceum Arts and Lectures Committee and private donations.
