Very sad news. "Roundabout" was one of my very first introductions to progressive rock. His bass playing and sound on that tune really surprised me as a young teen and along with Bruford's drumming, introduced me to a world of musicianship I couldn't even imagine existed. Very, very influential. An incredible legacy. RIP
90125 world tour was my first big concert as well. A virtuoso in every sense of the word. The drum & bass with Bruford on "Heart of the Sunrise" did a lot to make me think about the interplay between the rhythm section. Those two were making a musical composition with the bass as lead instrument - and a light bulb went off in my young little head. I still get goose bumps when I hear it some times.
top 5, I was a huge Yes fan, still am, musical genius for sure, those cats wrote some really great out of the box stuff, Yes is one of the reasons I love classic prog Rock, especially fond of his harmonies and writing. 67 is way too young these days
