Yes, like Elbow and Camel, are so much better live than on record. Rick Wakeman describes their albums as "sterile" and he is often right. The Union album is quite dreadful, but the tour that went with it, eight musicians playing for the music rather than themselves, the convenient doubling of everything except Bass & singer allowed songs like 'Awaken' to expand and evolve. The current state of play is that there are two bands called Yes, with 2 or 3 "proper" members each, and some extras. The whole mess is explained in detail at Henry Potts' site. Personally I could care less.

So with the advent of the interwebs (in my world) about 1999, I started looking backward, and catching up with what bands were doing. This was the heyday of the email newsletter and information and opinion about new releases and band activities was filtering through as never before. Yes had one and I subscribed, just in time for "The Ladder", another album with a fair bit of innovation, while remaining undeniably Yes. It's the best songs 'Homeworld (The Ladder)', and 'The Messenger' that work best and Bruce Fairbairn's production doesn't pander to their more noodly tendancies. The Ladder songs come properly alive on "House of Yes: Live from House of Blues" the album resulting from the following year's worth of touring. Some of the old stuff is given a makeover and Steve Howe manages to play on Trevor Rabin era songs, although he is far from happy about it.

So my weird conclusions are that Yes work best when a producer has a firm hand on the tiller. They thrived on innovation, particularly live. The best Yes music is song based and not about awesome musical technique. They were and probably still are a band ruled by their business decisions, rather than musical ones. Oh and Chris Squire is God's own Bass Player.

Yes (1969) A good bridge between the sixties and seventies, with a few cracking songs
Going For The One (1977) The return to songs after the noodling years
Drama (1980) Something new and different
Talk (1994) The best Rabin years album, with a good balance between his & Jon Anderson's influence
Keys To Ascension (1996) The best look back at the seventies, technology had caught up and the material was fresh after being set aside for a while.
House of Yes (2000) A contrasting look at old material and some new songs
I have to say I'm looking forward to Fly From Here - Return Trip in March 2018, same album with Trevor Horn taking lead vocals, the follow up to both Drama and The Buggles Adventures in Modern Recording which Yes fans should certainly hear. The best Yes album of the last 15 years is Anderson/Stolt's Invention of Knowledge,
With the blue touch paper lit I'm now retiring to a safe distance. Feel free to disagree with me...
