They all started in the 80’s and they’re still causing countless numbers of neck injuries from headbanging today.

It was announced that the Big 4 Festival; Metallica, Anthrax, Slayer and Megadeth will put on on massive metalpalooza in the US this year.

The moshing will commence April 23rd in California.  (thanks for making it accessible to us in the midwest!)

Rolling Stone reports the four bands have finally managed to put aside their differences to celebrate their shared thrash-metal legacy. “Most of the egos and sandbox issues from the Eighties and Nineties have dissipated,” says Metallica drummer Lars Ulrich. “We actually enjoy each others’ company and are comfortable celebrating the past while continuing our path into the future. It’s cool. Who would have known that anybody actually still gives a sh**? We’re very fortunate.”

That should be interesting considering that Dave Mustaine founded Megadeth in 1983 after he was told to leave Metallica. Tickets are $99 and go on sale Friday.
