I thought I'd throw in my two cents!
Alan White is definitely one of my all-time favorite drummers. Yes, Relayer
might be his best studio drumming performance with Yes (Tales From Topographic Oceans
was actually his first full studio recording with Yes).
I thought I'd include here a drum cover I did a while back. It's "Future Times/Rejoice" from Tormato.
I love that record, and even though at times it sounds slightly unpolished, I think it's one of the most underrated of Yes records, and of Progressive Rock in general.
I think I could play the song better today if I tried it again (I haven't played it in a while), but it's so hard that I was happy with it at the time! Enjoy.
