I have enjoyed Rush very much since I was but a lad. I remember being embarassed in about 1978 (when I was 14) that I had not discovered them earlier. I literally wore out the vinyl on the first half-dozen albums. First time (of many) that I saw them was on the Permanent Waves tour. Absolutely life-changing experience at that age.
Generally, I like the older, artsy stuff like 2112 and Hemispheres (largely because it resonates with memories of musical discovery). I also like some of the newer, heavier stuff on Counterparts and Test for Echo. Their music often makes me "feel" in ways that I cannot easily qualify. My wife thinks they're overindulgent, pompous and dissonant. She could be right.
They put on a great live show. I'd like to go again this summer, but concerts are a much bigger challenge than they used to be, with kids and all. My 7 year old son (Alex, but not after Lifeson) seems to really enjoy Rush, which is of no small comfort.
I'll probably get the DVD through Netflix and check it out.
