Back when I WAS a RUSH fan... it's been about 25 years... I don't now what it was exactly, they seemed so sophmoric and too humanistic for me. But I have to agree with the consenus on Farewell to Kings. I saw them on tour for that album, fall of 1977. Blew me away... but easily impressed at age 16. Unfortunately there were no good pressings of that recording.. it sounded distorted, noisy, rough. Maybe a Canadian import would have sounded better?
Also always liked "Trees" from Hemispheres.
