Don't get me wrong, as a musical theorist Cliff was perhaps the greatest member of Metallica. However, I don't think he was an absolutely amazing bassist. Ok, he invented a new style of bass playing, but most of his standard basslines were reallly nothing special, and you could argue he was just trying to play lead guitar on bass in his solos, so he wasn't much of a bassist. His technical ability really wasn't that amazing either, most guitarists can solo far better than he could. He is heavily overrated, on every video featuring him you get so many fanboys going "CLIFF WOZ THA BEST BASSIST EVA", which is really not the case. Perhaps if his life wasn't cut so short he would've been even better, but we'll never know. Perhaps the reason he's so overrated is because he died young. Still, he's one of my heroes.
I realise this may be treason to a lot of people...
