Hmm, depends which album.
I really like Into the Electric Castle but The Final Experiment is my fav.
Star One was one hell of an amazing gig, maybe you'd like to check that out, too. Other project then Ayreon, same concept writing and a bunch of diverse musicians. The mellow, off-rock projects he writes aren't exactly my cup of tea.
In the waaay early days, he used to play in Vengeance.
