Iggy, I'm familiar with all the Yes studio albums, except the first and Drama, and almost all of Jon's stuff (some of the best was together with Vangelis). However, I'm almost totally ignorant of all the other Yes side projects. Yes being your fave group, you're probably well-versed in all the side stuff too. I'd appreciate a lot if you could list some of the best albums in this respect and tell us why you think they're good.
ABWH was a good album.
Most of the side projects are less good imo.
Obviously Steve Howe did Asia and I quite liked the first 2 albums he was on.
i don't have any Bill Bruford.
I like many of Steve Howe's solo albums but you can guess what you are going to get acoustic, Jazzy stuff. Light walls is a nice collection of songs but not really proggy.
Chris Squires Conspiracy is Ok as is Fish out of water.
Not sure if Rick Wakeman has done any solo stuff
I think they needed to work together to bring out the best in them all the sum of the whole is greater than the sum of the parts.
I have a few Trevor Rabin Albums and 90124 is an interesting take on 90125. I saw him supporting someone in the early 80's (maybe Steve Hillage) and he was brilliant.
It is an interesting question though and one I hadn't really thought about I just collected stuff as and when I felt like it moire out of habit.
