Agreed. And if you dont already have Ayreons The Human Equation, definitely check this disc out. Marcela Bovios performance on THE was what inspired Arjen to create a whole project around her vocals.
She also has a CD or two with a prior band (Elfonia), although I havent been able to find any of these releases.
Another that I feel has a good sound/vibe is Penumbra. Been into them a couple years now. Anyone know what's happened with them lately? Are they still together?
