Disappointed that Signals got voted out - love the humor of that one, along with MP. My vote goes to 2112 - pretty plain in comparison to the choices left altho iconic. Had the cover been the starman, it would've been one of the top 3 Rush covers for me.
Grace Under Pressure
Seriously? That's their best album cover, IMO!
Y'all have some strange aesthetics tastes.
Roll the Bones (for the 3rd or 4th time)
I say the same for you brutha! Actually RtB is pretty cool, even if half the music on the album is not. I'd rate it towards the top personally. I think about the work Syme had to put into it, given that he couldn't cheat his way using Photoshop like he can today. (Yes I know Photoshop existed then, but it was pretty embryonic in comparison to what it is today - I've been working with PS since 1994, so I know from experience)
