Well if I go and see a band with Billy Sheehan, Stu Hamm, or Victor Wooten, I'm probably going to want a bass solo at some point.
If I saw Iron Maiden, and Steve Murray just stood at the back not moving, I'd be quite disappointed.
If I saw Motley Crue or Kiss, and there was no fire or pyro involving the bassist, again I'd be disappointed.
If I see a Psychobilly band, I'd want the bassist to at least spin his DB a couple of times.
So it all depends...
