As cool as it would be, he's pretty committed to Lamb of God. They're one of the largest metal acts in the world so I don't see him leaving anytime soon.
I guess I worded that weird. I'm not in any way expecting Adler to leave LOG... and I don't see him playing for both bands. I'm sure he's just playing as a studio drummer on this album, but I'm wondering who they'll get to replace Moe long term.
