Geoff Castellucci

I recently came across singer Geoff Castellucci and was very impressed. He is not just a spectacularly low bass singer but has a lovely upper range (he calls himself a baritone who happens to have a bass range) added to a soaring falsetto which means he can basically multi-track himself into an entire barbershop quartet. And he also happens to have an expressive, humorous face and acting talent to go with it:

Brilliant production of the "Oogie Boogie Song" from "Nightmare Before Christmas" (a film I don't even much like...) starring Geoff:

[Edit: and "The Headless Horseman" as well. It's not just good singing, it's good performance. https://www.youtube.com/watch?v=8rrg0ksSQdw ]


Also, Freddie Mercury sings soprano: https://www.youtube.com/watch?v=4gO8rPCBo8o
I was never much impressed by his famous collaboration with Montserrat Caballé (which just makes the artificiality of opera all the more incongruous), but this is astonishing -- this must be what the great castrati sounded like, neither the ethereal tone of a counter-tenor nor the clarion ring of a tenor, but the soprano range with a full male physique behind it.
