I missed the countdown thread. I got into Rush late, sadly.
I started to have interest in the mid-1990s. I bought Test for Echo, liked it, but had to pass on the tour (a big regret) because I was in college and didn't have the money. Then Rush went away, and when they came back, I was at law school in Massachusetts and me and some buddies went to the "comeback" show in Hartford. I still wasn't a massive fan, and wasn't as "into" them as everyone else. But after that show, I started to be. I bought more records, saw them a couple more times, and became a hardcore fan. Sadly, their last two tours (Clockwork and R40) were in San Jose, which from where I live, is a non-starter on a weeknight. I SHOULD HAVE gone, obviously, but with the traffic, it would have been a ridiculous haul. Still, now, I wish I had.
My favorites right off the top of my head are Animate and Red Sector A Distant Early Warning. Those two always resonate.
edit. I misspoke and confused the two. But Red Sector A is in my top-10 for sure.
