OK. I have been reading this thread and biting my tongue but I finally felt compelled to post.
I knew Cliff. Long before his Metallica days, when he was playing in local Hayward/Castro Valley Bands like EZ Street and Agents of Misfortune. In fact, Cliff gave me my first unofficial bass lesson on his old Rickenbacker. He was 19 -- I was 15. 27 years later, I am still playing bass.
Was Cliff a great bass player in the sense of a Stanley Clarke or Victor Wooten? The answer is No. Truth is most any bass player who has an interest in hard music and is willing to develop his finger speed and invest in a Morley Power Wah Fuzz could copy every Cliff Burton solo note for note. But they would never be great like Cliff.
Cliff was (and is) one of the greatest bass players I have ever seen (or heard). And he deserves to be remembered as such. Here's why.
As a performer - he was amazing. Cliff through his entire body into his playing. His head whipped as if it were on a swivel. His body wrapped around his bass as if it was an internal organ. It was wild and cool. No one AND I MEAN NO ONE, could infuse a crowd with such reckless enthusiasm as did Cliff. Guitarists who were used to going to metal shows to watch the lead guitarist to cop their riffs would purposely move to Cliff's side of the stage to watch what he was doing. We all know when a performer is "On" and when they are just mailing it in. Cliff was always "On." I dare anyone out there to honestly tell me that they saw Cliff play live in person and that it was uninspired. He loved to play bass. He loved it with every ounce of his being. And it showed like no-one I had ever seen before or since.
Cliff's other area of greatness was in his ability to compose heavy music. Kill em All -- Ride the Lightning -- Master of Puppets. Who else recorded epic 10 minute songs like this? Mini-operas. No one. And no one has since. Not even Metallica since Cliff died. Why? Because Cliff was the architect of that sound. With all due respect to James "Dr. H" Hetfield, and Lars and Kirk, the sound of those first few albums is really Cliff's vision. Cliff loved classical music. He loved the way that Bach and Wagner could compose music that sounded like a descent into hell and back. Cliff got it. He figured out exactly what the great classical composers had done and he took it out of the symphony and applied it to a four-piece guitar(s), drum and bass. That music is timeless. Just like Bach and Wagner, because it comes from the same place.
What might Metallica sound like today if Cliff were still alive? What other compositions would he have created? I wish I knew, because I know it would have been inspired and musical and honest.
Cliff died in 1986 at the age of 24. What have most of us accomplished by our 24th birthdays? He contributed so much already and was far from burning out. I think people see him as "GREAT" because of that incredible loss of potential. For whatever reason, I understand it.
Cliff Burton was not a master of the Bass guitar. Not like Stanley or Jaco or maybe even some of you. But he truly was one of the best bass players I ever saw or heard and I am proud to say, the best I have ever known.
