Some of the biggest names in metal have lined up to form a supergroup called the Metal Allstars.
Phil Anselmo (ex-Pantera, Down), Joey Belladonna (Anthrax), Max Cavalera (Soulfly, ex-Sepultura) and Udo Dirkschneider (UDO, ex-Accept) will front the band on a tour of South America in November.
They'll be joined by Jon Donais of Anthrax and Shadows Fall, Brian Fair and Matt Bachand of Shadows Fall, Jasin Todd of Shinedown and Aaron Rossi of Ministry.
And more names are set to be announced for the trip, which will raise funds for the charity Ride For Dime, set up in memory of murdered Pantera guitarist Dimebag.
Calavera says: "I'm so proud to announce the coming of the supergroup. We're going to have great fun and there's going to be amazing metal. Everybody knows I love collaboration – this one's going to be exceptional."
