the Farewell To Kings title track and Xanadu are both excellent. Two of Rush's best prog tracks. The rest is more for the hardcore fans (kind of like the songs on side 2 of 2112). A lot of people hate Cygnus X-1 cus its got the most over the top geddy vocals and some of Neil's silliest lyrics, but if you enjoy songs like The Necromancer or By Tor and the Snow Dog then you might get a kick out of it. and Closer To The Heart, Cinderella Man, and Madrigal are middling art-rock pop songs, your mileage may vary.
I suddenly got back into Dream Theater this month. Dunno what drove me to revisit them. I'm especially making sure to check out the albums I didn't know as well. I've been liking them way more than I used to. There was a lot more to them than I remembered there being.
