Watch Lars Ulrich Drumming With Mumford & Sons

This weekend, at Austin City Limits festival in Texas, folk-rock supremos Mumford & Sons headlined the closing night in Zilker Park, Austin.

So what? You're probably asking. They have nothing to do with Kerrang!. And normally you'd be right, but not when Metallica's Lars Ulrich is involved!

To close the main set before the encore, the Metallica sticksman entered the fray to play drums on Mumford & Sons' 2015 track The Wolf – to the elation of the thousands in attendance, as you can see in the video below.

"So fucking cool to share the stage with Mumford & Sons and bash away on their awesome song The Wolf at ACL last night," posted Lars on Instagram.

"Thank you for encouraging me to come up and fuckin rock with you.... Fun times fellas!"

Metallica recently announced that they would be headlining five different Danny Wimmer festivals in the United States – playing two different sets at each festival!

“What a day for DWP and the fans of our festivals,” said festival promoter Danny Wimmer. “As a fan of this band, I still get goosebumps walking into Metallica’s headquarters…I spent a lot of times with the fans and I asked them, ‘What do you want to see?’ And nine out of ten times, they said Metallica.”

Here's where you can catch Metallica in the States next year:

• Epicenter - May 1-3 - Concord, North Carolina
• Welcome To Rockville - May 8-10 - Daytona Beach, Florida
• Sonic Temple - May 15-17 - Columbus, Ohio
• Louder Than Life - Sept 18-20 - Louisville, Kentucky
• Aftershock - October 9-11 - Sacramento, California

Metallica were recently forced to cancel their trip to Australia and New Zealand with Slipknot after frontman James Hetfield was entered into rehab.

Speaking to USA Today, Lars said in response to inquiries about James’ current status, “He’s doing what he needs to; he’s in the process of healing himself. I feel bad for everybody down in Australia and New Zealand, but we’re excited to get back to full force and come back stronger and healthier than ever. Along the way, there’s obviously an occasional bump in the road. But it’s been an incredible ride, and we’re looking forward to getting back down there, hopefully next year.”
