Ok, I read something about that album a while ago and was thinking if Rick Wakeman really could play fusion. All I have heard him play is classical inspired arpeggios, and in a rather stiff way if you ask me. But I could give that album a shot just to hear how he handles that style of music.
I think I get what you mean by beeing nervous by hearing Steve play. Some solos he does sounds a bit sloppy or hard for him to play and not that precise. But he can also play the most wonderful stuff. He's not as - for example, Allan Holdsworth, who always does great stuff on his guitar.
