Evanescence: Whats with the backup singers?

I don't really like Evanaesence that much, and this doesn't have much to do with the thread, but next time you go to see them live, make sure 'Full Scale' are supporting them, they will outshine the main act many times over, so much so in fact I am considering going to go see Evanaesence just for them. They are a great Aussie band, the far right logo in my sig.
