The loudest band of all time is Motörhead. Feel free to argue with me about that. But thanks to the fact that I once saw Lemmy and Co., you’ll have to speak up when you do it.

Anyhoo, if there is one tour that might collectively challenge Motörhead’s decibel count, it’s the forthcoming thrash-tastic team-up of Metallica, Slayer, Anthrax, and Megadeth. That’s right, according to Billboard, the Big Four of thrash metal will be playing together this summer in Europe. Megadeth head honcho Dave Mustaine is describing the shows as a “once-in-a-lifetime opportunity for heavy metal fans to see the four greatest heavy metal bands in American history,” on one stage. There’s no word on U.S. dates as yet. But with a prevailing wind, East Coasters will probably be able to hear their sets blasting across the Atlantic.

Do you agree that they are the four greatest heavy metal bands in American history? Would you consider heading to Europe to see the shows? And would you wear ear plugs at the shows? Let us know!
