I created this topic in the hope, that there are many metal music fans here, who enjoy metal covers of classical pieces. If You have a nice youtube video, please don't hide it from us.

<Added>

Edit: Orchestral covers of metal songs are also welcome :-)

As a starter here is the first one I listened to:

Children of Bodom: Vivaldi: Fous seasons, Summer Theme

Secondly, here is a cover in the opposite direction:

Vedres Csaba and the Kairosz quartet: System of a Down: Toxicity
