Two of thrash metal's finest make it to the quarterfinals of our Greatest Metal Bassist competition. Get ready for this 'Big 4' battle.

Can anyone defeat late Metallica bassist Cliff Burton in this tournament? Our readers have been relentless in their support of Burton ever since the competition started. The classic Metallica floor shaker has crushed Napalm Death's Shane Embury and Symphony X's Michael LePond so far, but can Burton beat out a fellow thrash legend?

Megadeth's David Ellefson has moved into the quarterfinals, defeating two very worthy opponents so far. Ellefson beat out Atheist's Roger Patterson in Round 1 and former Metallica powerhouse Jason Newsted on Round 2. Having already defeated a beloved Metallica bassist, will Ellefson be able to best yet another?

Cliff Burton or David Ellefson? Vote for your favorite bassist in the poll below! Voting for this round closes on Sunday, Oct. 13 at 11:59PM ET. Fans can vote once per hour, so keep coming back to make sure that your favorite metal musician wins!
