Some of these covers do absolutely nothing for me.
My faves, in sorta order:
1. Grace Under Pressure (go figure, it's my least favorite Rush album)
2. Tales From Topographic Oceans (Drama a close second)
3. Powerslave
4. Rock And Roll Over (Dressed To Kill a close second)
5. Rising
6. Killing Machine (Hell Bent For Leather for our US friends)
I never noticed the "In Rainbows" cover like that. Pretty cool.
