A surprising, or maybe not so surprising, number of metal bands, and song writers have borrowed heavily from classical. No end of interviews with rock guitarists where they talk of listening to some violin piece and wanting to honour or duplicate in on the guitar. No end of albums with a rock cover of some classical piece, from The Agonist's a capella of Swan Lake through several Pachelbel's Canon in D, etc. Not forgetting a good few borrowing from the folk canon, and I don't just mean late era Rainbow after Ritchie got his new girlfriend. :)
