I have always heard people say that Rush is one of their favorite bands, but I honestly don't like them. I don't like his voice and I don't really like their style of music. I haven't really liked much of anything they have made, except maybe Tom Sawyer, and I'm not even a huge fan of that song.
Late 70s was kind of a transition, I think, into more hard rock bands that made up the 80s, like ACDC and Metallica. I like mainly music from the beginning of the Beatles to the mid-70s. Rush sounds too much like 80s music to me, which I don't really like. Same goes for other bands like ACDC. I'm not a hard rock guy, I am more of a progressive rock guy.
I added some Rush albums, anyways, for you guys.
EDIT:
Dude, Division Bell was released in the 90's.
Yeah, but it's still a good album, made by a band that was most popular in the 70s. The first time I listened to it, I didn't know that it was a album released in the 90s.
Also, the "(60s-70s rock)" doesn't mean that everything in this topic has to have been made in that time period. I'll take things well into the 80s as long as they are as good as and sound similar to things from the 60s and 70s. I put that because probably 95% of the stuff in this topic is made in that time period. When I say "60s-70s", I really mean that it sounds like it came out of that time period. It's really up to what I think.
