In my time its Geddy Lee and Chris Squire. I saw them many time's since the late 70s.Most recently...Geddy Lee with the Clockwork Angels tour. In August of 2013 I saw the so called Yes....even though they were pretty good. They can never really be Yes without Jon and Rick.
Best rock bass player
Today is the 11th anniversary of John Entwistle's death. I had the pleasure of seeing him play live a few times and was always impressed by his musicality and ability to keep up with Keith Moon- much less lay a foundation for Pete Townshend. I also have always enjoyed Chris Squire, Stanley Clarke, and Flea for similar reasons. Who are some of your favorites?
