In my unfinished "epic" Bittersweet Seeds story (to be a screenplay / storyboard / animatic / feature), I have Miserere and Spem in alium in key scenes, potentially, for the soundtrack. Naturally all elements may change until it's final - as I have other alternatives in mind too, in case one "theme" works better in the end than another. To my point, for this potential particular "chorale theme" I'm still looking for more great epic choral pieces and soundscapes of a variety of moods, not just this churchy/funeral kind of stuff. I'm generally not into opera or choral music (among a few other genres), yet I know of some excellent potential candidates that don't stereotypically bug me. Suggestions very welcomed.

Also, FYI, my story is not about religion at all, however people die, and there's the potential of a God-like A.I.
