Once Bruford quit, it was all downhill. His percussion on the earlier Yes albums was incredible.
Yes, Bruford did great work with Yes, Genesis and King Crimson.
Yes is also my favorite band, and I love Bruford’s drumming. He's amazing. That said, Alan White is no slouch. His drumming on Sound Chaser, for example, with the timing switches in the later parts of that song is wonderful.
