"Villa" is probably my favorite Rush instrumental (or Leave That Thing Alone).
And your husband is right. Anyone that can play any of Rush's stuff can play anything else in the field. Now that I can play alot of Rush on bass, I find most other things basic because no band puts into their stuff like Neil, Geddy and Alex put into.
And if I was being completely honest, when i first discovered Rush, I fell asleep at my desk (I was listening to 2112 in it's entirety, fell asleep at 'Discovery'. Once 'Something for Nothing' came on, it got me up right away).
I also saw the Time Machine Tour (my second concert ever- after Iron Maiden) and thought it was phenomenal. I was in Toronto, and it was just packed. They play as good as they did back when they released Moving Pictures.
