It might be cheating, but right now it might actually be Re-Kill, or even Double Live Annihilation that I posted a few days ago. The Re-Kill version of "Stonewall" has been stuck in my head all day long, and what an incredible solo. But for a more conventional answer, I'm really not sure. Probably one of the first two, but I haven't spent quite enough time with either for one to pop yet. They're one of those bands that I've always liked but didn't get into my rotation to familiarize myself with, so this current binge is helping with that.
