Unofficially (in my opinion), all the bands listed except Jethro Tull, would be categorized as Progressive Rock. A long time ago there was a term, Art Rock, which I haven't heard used in over 20 years. One may be tempted to group those bands under the Classic Rock category, but I understand the original intent of the question is to differentiate Yes, et al, from other Classic Rock bands like Led Zeppelin and Journey. Again, just my opinion.
