/jp/ - Otaku Culture

Okay.. So there's this voice sample that I've heard in a few different Touhou songs, mainly Amane/Rolling Contact.
The thing is, the voice makes my heart skip a beat, sends chills down my spine.. I havn#'t been able to stop comming back to re-listen to the beautiful voice for the 2~3 years I've known about it..

If any /jp/sie knows more about this.. voice.. thing, like its origin, or more songs which use it. It'd be highly appreciated.

TL;DR
Beautiful voice sample I'm inlove with, Where the hell is it from/more of it?

Also, post anything you have an unnatural love/likeness for

Can anyone tell me how/where I can get an English only Vocaloid, if such exists? If not, would I be able to get Luka at a local convention, as she's bi-lingual? Would her menus be in Japanese only?
