Continuing our week-long look at some of the greatest rock & roll bass players of all time...today we shine the spotlight on John Entwistle of The Who. With Townshend’s guitar and Moon’s drums providing the only other instrumentation...Entwistle’s furious bass lines and bombastic sound gave The Who’s music a thunderous foundation. During this 1999 performance of “5:15″ that I’ve shared below...the mesmerizing improvised Entwistle bass solo absolutely steals the show.
