File this under huge rumor. In a recent interview with Metal Hammer, Kerry King yapped about the possibility of thrash's big four (that's METALLICA, MEGADETH, SLAYER and ANTHRAX) could be touring together soon:

“I’ve heard people referencing Lars,” says King. “I don’t know Lars that well and I haven’t heard it from Lars but apparently he’s talking to somebody about it. Maybe us, Metallica, Megadeth (and), I think he even threw in Anthrax and I said in this day and age, I know we had that time together but how do you leave out Machine Head? There’s better options than Anthrax and that’s nothing against Anthrax, but they’ve just been in pieces for quite some time and that doesn’t make as much sense to me.”

Ok, as you can see, King is already talking shit on Anthrax. Besides that, I just NEVER EVER see this happening. Dave Mustaine hates Lars and Metallica with all his being. You expect him to actually open for them? Because that's the only way it would happen, with Metallica on top. And then, Slayer open for Megadeth? And Anthrax as the opener to the whole thing? Personally, I think there are far too many egos involved for any of this to happen. But, if there is some slight chance that this would happen, I will be first in line to check out the show!

Ok, we may not agree on the new Metallica single (live pro-shot video above btw) but I think we can agree to this. Metallica is no longer a metal band. They are a tolerable hard rock band. I considered the song a great hard rock song. Guitarist Kirk Hammett apparently disagrees. In an outtake from a recent interview with Revolver this happened:

Are you guys shocked that you’re still the biggest metal band in the world?
I’m pretty shocked, yeah. I think about it a lot. I think, Will there ever be a band like us to follow in our footsteps? But then I think about it and I thought, Was there a band to follow in the footsteps of the Rolling Stones? Was there a band to follow in the footsteps of Led Zeppelin? So, maybe I’m just thinking the impossible. But there still needs to be a new modern band that has the impact, and they haven’t showed up yet. Or maybe they’re out there and I just haven’t heard them yet.

It seems like there’s been bands that seem like they have the potential-you know, Pantera, Lamb of God…
…Slipknot, Korn, yeah. But it just doesn’t happen for whatever reason. My brother-in-law came up to me and was like, “Are there any bands who are in their 20s that you guys are intimidated by?” And I thought about it long and hard and I’m like, “No.” I wish there was, you know. I wish there was because it would give us a nice challenge and motivate us to maybe step up to their plate, whatever their plate might be. It just hasn’t happened yet.
