Classical music has been a part of metal since forever. Where else can you get a killer noodly guitar solo without having to make it yourself? But then you get guys like Chris Impelliteri who takes the style and turns it metal.
I think there’s a harpsichord in this, which helps reinforce the 17th centuriness of it. But it’s a soaring noodly two and a half minutes of fun. I assume this is what the Skwisgaar Skwigelf Advanced Fast Hand Finger Wizard Master Class would be.
And I really can’t talk about incorporating classical music into metal without mentioning the time Ghenghis Khan totally ravaged Oshmans.
