Very good guitarist for Metallica. There are better though, like Vai, Satch, Petrucci though.

Guitarist for metal band metallica. Started guitar at age 15 playing in a few bands, most famous are probably exodus, he then was asked to join metallica.

A famous guitarist in the metal world, even though he isn't very impressive, most of his guitar solos are very average and he is praised only because metallica are the most famous metal band.

For some other better metal guitarists, listen to marty friedman or dimebag darrell
