This is Hidaritsuu, otherwise known as CasteP in the Vocaloid community, a lefty 7 stringer musician from Canada. His thing is speed metal and more than anything, he likes making sweet solos. The whole production (instruments, composition and mix) really speaks to his professionalism. He usually writes lyrics of all sorts of themes... along with some pervy stuff. If you find yourself craving some Vocaloid metal, then his music is what you need.
