Reddit mentions of Live at Summit Studios Denver Mar 12

My favorite Yes album is Relayer, so I'd definitely get that one next. I know most people hate Tormato and Drama, but I happen to like them both quite a bit. I basically like everything Yes from 1969-1983.

Another one that gets overlooked in Yes' catalog is the debut. That album is a lot jazzier (due to Peter Banks' guitar work), and the songwriting is a bit less prog-oriented, but awesome nonetheless.

With King Crimson, I'd basically recommend everything else (I'm a fanboy; bite me, haha). Most importantly, I'd go for Discipline and In the Wake first.

Also, pick up as many live albums as you can from KC. They were always a very interesting live act. The Larks' Tongues and Red lineup were probably the best out of the bunch in regards to live performance, but the 80's lineup weren't slackers by any means.

Here's a good place to start with live albums:

The Collectable King Crimson, Volume 1 (Live at Mainz; Live in Asbury Park)

Live at Summit Studios March 12, 1972

These are two of my favorite bands, and I'm probably a little biased in my recommendations, but this should be enough for someone relatively new to them to be content.
