I read an interview from an older time that Rhapsody was too expensive, especially due to the hired musicians on stage (which now is only Dominick).. I would LOVE to see Rhapsody there. I just don't understand if Nightwish could do it, and Stratovarius (who at the time of commenting on Rhapsody) Glenn hadn't gotten Strato due to prices, I guess.. I'm sure something can be done with Rhapsody. Then again, Demaio is behind them..
Possibilities may be endless so still I will hope someday to be lucky to see them at Progpower. They're like my favorite band, but I have seen them, I would love to see Blind Guardian, Helloween, Dark Moor (especially with Elisa....), and Nightwish.
