About a dozen years ago, around the time I started writing my opera Sister Beatrice, I became interested in Hindemith's 1921 Opera Sancta Susanna, a work he set to a 1914 play by August Stramm. There were no recordings available in 2002, and, because of the sacrilegious nature of the work and non-availability of the music, nobody performed it. All I could get my hands on (through interlibrary loan) was a piano-vocal score.
Now (as of yesterday) both the piano-vocal score and the orchestral score of this unusual and brilliant one-act opera are in the IMSLP (the music is now in the public domain in America).
This recording (not a video, but it does have subtitles) of the prelude and the final scene is the best performance I have found. Since my first "viewing" of the opera was in the theater inside my head, no staging I have seen on the half a dozen YouTube videos lives up to the staging I imagined, but Hindemith's orchestration surpasses my imagination.
If you have any interest in my Sister Beatrice (which, even though it was published in 2006, still hasn't had a performance outside of the theater inside my brain), you can hear a computer generated recording (with brass instruments as the vocalists) on this page of my Thematic Catalog or through these links.
