I was reminded of this artist just a few minutes ago. I did a search, and nothing came up. I am also not entirely sure if I would class this as "strictly" classical, but he plays the violin, so I just went with it. David Garrett is a concert violinist who is best known for a lot of metal and rock covers from Metallica, ACDC, and Led Zeppelin and many others, just search youtube and you'll find a lot of his work. He's also released a CD by the name of Rock Symphony.
Listen for yourself and allow your ears to be filled with the awesomeness that is David Garrett:
