And while it at first seemed Adler was onboard for recording duties only, he has since agreed to play as many live shows as possible. But whatever happens, he has promised Randy Blythe and co that he is going nowhere as far as Lamb Of God is concerned.

He tells The Jasta Show: "The first thing I did after I had that conversation with Dave was to get in touch with the guys and just see, 'How does everybody feel about this? I don't want it to come across as a threat. I don't want this to feel like I'm leaving or anything.'

"And everybody was stoked. Because they know. They just know. I'm up until 4am every day listening to Megadeth. So, they were, like, 'Dude, it's amazing. Good for you.'

"If ever it came to a point where there was a question of this or that, it's gonna be Lamb Of God. Lamb Of God is my baby. Being in Megadeth is kind of like I'm helping babysit somebody else's kid. I love being there, but that's not where home is."
