10 Awesome Supergroups We Never Got To See

10. Metalli - Primus

There will probably never be another metal bassist who can really hold a candle to Cliff Burton. Though he was taken from us just after the release of Metallica's third album Master of Puppets, his vast knowledge of harmony and eclectic musical taste left a legacy on the four-string community going forward. While Jason Newsted did the best that he could filling that slot on And Justice For All, we almost had a slightly funkier bassist at the helm.

During the interim period where Metallica was auditioning bass players before touring, Kirk Hammett had originally suggested his high school friend Les Claypool try out, considering how talented a player he was in their salad days. As James Hetfield is quick to point out now though, the chemistry was never really there, with Claypool having the ability to play circles around the rest of the group.

Then again, it would have been incredibly interesting to see what Primus' unique brand of weird would have been like when working off of Hetfield's heavy as hell riffs. It's not like Claypool harbors any resentment for not being chosen either, with him busting out his own bassified version of Master of Puppets from time to time. For as much as the music world is better off with both Metallica and Primus as their own entities, there's probably an alternate timeline wear Metallica became the progenitors of funk metal.
