Get ready for an insanely difficult decision in this Round 2 battle between two ultra-technical wizards.

The metal masses have a universal respect for Sadus / Testament / Death bassist Steve DiGiorgio. One of the most technical metal bassists on the planet, DiGiorgio is a superhuman on the instrument. Although the man fits the bill for metal, DiGiorgio's style is heavily based in jazz-fusion, as is his opponent in Round 2.

Dream Theater's John Myung is one of the favorites to take this entire competition, proving his popularity early with a big win over Cynic bass master Sean Malone. For nearly 30 years, Myung has played the bass and the chapman stick for Dream Theater, creating a deserved reputation as an untouchable prog musician.
