Metallica is once again asking its fans to do something pretty badass: give blood. 🤘🩸

The band is teaming up with the American Red Cross for the fifth time, this time around their upcoming Life Burns Faster residency at the Sphere in Las Vegas.

The Red Cross x Metallica Blood Donation Experience opens September 28 at Fashion Show Las Vegas and runs through March 19. Metallica kicks off its Sphere residency October 1.

And because this is Metallica, they're not exactly making this a boring trip to the blood bank.

The donation center will be loaded with Metallica memorabilia and artwork, plus a replica of the drum kit Lars Ulrich used on one of the band's tours. Donate blood and you'll score a limited-edition T-shirt designed by Squindo — and you'll automatically be entered for a chance to win that replica Lars drum kit.

Metallica fans have already donated more than 90,000 units of blood through the band's previous Red Cross campaigns over the past year and a half.

So yeah… Metallica wants your blood. But this time, they're actually going to a good cause with it.
