yeah, I've heard this one band... using a violin... but it sounds way more awesome, rather than adding a violin to a metal band, but to add an electric guitar to a classical type thing.. I heard this one band, they played classical music on an electric guitar with effects, it sounded awesome... it's like "re-mixing" soft calming slow songs into hard and heavy sounding, but still with the melody of the classical... it's hard to explain, but it was awesome.. I was going to look up some classical music to try on my electric guitar, but haven't gotten around to actually looking any up yet...
