Mustaine tells VH1 Classic Rock Icons (via Blabbermouth): "There was a feeling that James and I had when we would stand next to each other and play. I think people saw there was a real brotherhood there. We were a really great guitar duo."

He was fired from Metallica in 1983 before the release of Kill 'Em All and says his anger at that decision drove him to make Megadeth the most "ultra-furious metal band" in the world.

Mustaine continues: "Growing up and having all of the defence mechanisms I'd gotten over the years, I was pissed - I was going to fight. When you're scratching and clawing to have something to eat, someone takes away your livelihood, this means war.
