This question started me thinking the other day. Would RUSH have made it another 30 years after Hemispheres without PeW & MP as a transition between Prog and the Keyboard Era? If Hemispheres would have led straight into Signals would the Older RUSH fans accepted the new and would the newer fans accepted the old? I think they would have made it but with two fans bases in tow. There would always have been a division between the fans. Old and New! I think PeW and MP were the two albums that allowed for a much smoother transition. The Bridge if you will, between the old and New.
