Er, everybody needs to know 2112. Best concept album ever written IMHO. But at the end the Elder race returns, and assumes control over the Federation.
Lot of sci-fi prophetic futurist stuff in Rush songs. If Anons are not familiar, check out:
Red Barchetta
The Camera Eye
Witch Hunt
New World Man
(many more)
Not to mention – LIVE, those same 3 guys can reproduce the albums to perfection! Amazing
