It's funny how many different Rush albums people have placed up there...(of course, they've only done like 30 or something)...
I used to be a huge Rush Head....But I've not brought any of my collection to Australia
My least favorite Rush album was probably "Roll the Bones"...
My top 3 are probably:
Moving Pictures
Hemispheres
Grace Under Pressure
Completely different sounds on each...
Moving Pictures, IMO, just defines Rush as the amazing trio that they are...the songs are intricate, yet melodic...Tom Sawyer, Red Barchetta, and YYZ are classics!
Hemispheres is a bit more of a "jam", the music isn't as clean (as was much of their earlier stuff), but the playing is masterful and "Spirit of the Radio" is just an amazing song, period!
Grace Under Pressure - Rush's first step into their more "modern" sound, IMO..."Distant Early Warning" sets the tone for this album...Rush's musical theatrics are maintained in this album...but there's something about the structures of the songs that is different....synth sounds, cleaner guitar sounds, and percussion is quite different, as well...
Man, you could do a 500 post thread about Rush's body of work alone.
