So fucking good live, saw them when they last visited Dallas and was blown away. I have always been a guitarist, but Mario always made me want to pick up some drumsticks.
I'm looking forward to Mastodon as well. I've seen them once before, but the sound mixing was absolutely awful. I'm hoping that since they're co-headliners rather than an opener (as they were last time) that they'll have it dialed in a bit better.
