His singing voice reminds me of HYDE/larc en ciel and maybe a few other Japanese singers. I've never heard a song from an English speaker with this quality before and I can't tell if it's a language thing or actually a particular technique.

Does anyone know what I mean?

Is this a type of vocal style with a name? I'd love to read more about it.
