Rimsky-Korsakov's one-act opera "The Noblewoman Vera Sheloga," intended as a prologue to his earlier full-length opera "The Maid of Pskov." Performed in 1997 at the Moscow Conservatory, presumably with students in the singing roles. This is a semi-staged production with orchestral accompaniment. Given that the overture is omitted among this numbered set of YouTube videos, I've added a link to another video (with still image) of the audio for the overture.
