Metallica have replaced Green Day at New Orleans' Voodoo Music & Art Experience later this month.
The heavy metal band have stepped in to headline Saturday, October 27 while Green Day's Billie Joe Armstrong focuses on his rehabilitation process. Metallica revealed they agreed to take over the slot to "help out" fellow singer.
Guitarist Kirk Hammet told Fuse: "We discussed it between the four of us and we all said, 'Yeah'. It would be a great thing for us to do and it would also be great to help out Billie Joe because he's a friend of ours and we love Green Day. If we can help them out in any way possible, we're always happy to do it because we love those guys."
Meanwhile, in a statement, drummer Lars Ulrich said: "Our good friends and fellow Bay Area residents Green Day had to unfortunately cancel their plans to be there, so we are more than happy to fill in for them in our own unique way."
Billie Joe Armstrong checked himself into rehab for substance abuse last month after an onstage meltdown during the band's performance at iHeartRadio Music Festival in Las Vegas. Green Day bassist Mike Dirnt subsequently insisted that the band had been forced to amend plans so they could "put the life of our friend in front of everything" but was adamant that the singer would pull through despite his current issues, adding: "We're still getting ready for the next phase."
The rest of the "¡Uno!, ¡Dos!, ¡Tré!" album trilogy will be released in two more stages, with the second LP, "¡Dos!" coming out on November 12 and "¡Tré!" on January 14, 2013. Green Day will also play a huge UK stadium show next summer. The trio will headline London's 60,000 capacity Emirates Stadium on June 1, 2013.
