I agree, Jethro Tull is very good. I saw them in Hershey PA in 1996 (they split a concert with ELP) and they were outstanding.

Admittedly, I haven't listened much to U.H.

I like Queen very much, though they are very different than a group like Rush. I really would not put Queen in the same league when it comes to skills as musicians - but Queen had great performances and catchy songs.

I am a big fan of Yes and ELP (I would say my three favorites in order are Rush, Yes, and ELP). But what separates Rush from the other two is that Rush has gotten BETTER over time. Their last album (ClockWork Angels) has several tracks that are just incredible. The signature work of Yes lasted much shorter (from the Yes album to Tormato), and the signature work of ELP lasted even shorter (they really had four outstanding albums, but MAN were they outstanding)

You mentioned Styx. They had a period of good albums, from Equinox to Paradise Theater. Good but not great....had they voted Dennis DeYoung off the island long ago they could have produced better material. Stuff like "Babe" and "First Time" and that idiotic Mr. Roboto crap was just bloody awful.

I think SuperTramp was vastly underrated in the U.S. Don't know if you knew this, but the long-time producer for Supertramp helped Rush produce their 1989 album, "Presto"

I like individual Stones songs. And I certainly like some of the early Pink Floyd albums.
