Unfortunately,no, I have never seen any in concert. But, the band's I listen to are as follows: Evanescence, Within Temptation, Nightwish, and a couple of others (but I'm too tired to remember what they're called apparently.) I clips if you symphonic metal as and strong rock and roll music with orchestral instruments, so the range can be pretty broad. And some of these mat not actually be classified as such by society.
