I have long believed that TAAB was the best “prog-rock” album ever.

Thing is, some people’s definition of ProgRock don’t match other peoples.

But I would include Yes, ELP, King Crimson, Pink Floyd, Jethro Tull, and some others.

Burnt Weeny Sandwich and Uncle Meat by The Mothers Of Invention are the most inventive prog albums of all time for my money, and elements of both albums border on jazz/rock fusion as well. Zappa's output was mind-blowing, but he was all over the musical board...it's tough for people to give props to a guy who did just about everything as well as it could be done (albeit with a bizarre spin) every time.

There is a current band from England called Elbow that bills itself as "prog rock without the guitar solos." They are pretty decent.
