I'd be amazing to hear Evanescence with Josh Groban. I totally adore him and his angelic voice
It would be nice too to hear Ev with Tori Amos, KoRn (not just Amy), Green Day, Coldplay (
), Lifehouse, Lisa Gerrard (she sang on 'Gladiator' soundtrack)... and it'll be awesome to hear Ev on soundtrack for some nice movie.
