During METALLICA's May 22 concert at Deutsche Bank Park in Frankfurt, Germany, guitarist Kirk Hammett and bassist Robert Trujillo performed a cover of "Schwarz-Weiß Wie Schnee" (English-language translation: "Black And White As Snow") on TANKARD's version of the anthem of the German football club Eintracht Frankfurt.

Fan-filmed video of the performance can be seen below.

METALLICA launched the "M72" world tour in Amsterdam in April 2023 and has since performed for an estimated four million fans worldwide.

As with all tour dates, the band is donating a portion of ticket sales to local charities through METALLICA's All Within My Hands foundation.

Established in 2017, the foundation has raised more than $20 million, supporting vocational and technical education, food insecurity relief and disaster response initiatives.

The "doodles," as Hammett and Trujillo refer to them in their setlists, are pared-down interpretations of popular songs from some of METALLICA's musical heroes.

During a 2020 appearance on "Drinks With Johnny," the Internet TV show hosted by AVENGED SEVENFOLD bassist Johnny Christ, Trujillo stated about how the idea for the "doodle" came about: "We were in Europe — this wasn't the last European tour, but the tour before that.

We were in Amsterdam, and we had tried a couple of...

There was a duet moment, where we were supposed to play a METALLICA song that's maybe, like, a deep cut, so we'd play 'I Disappear' or something, and we started noticing that we weren't getting the result we wanted.

It was, like, we'd go up there and we'd start playing, like, 'Eye Of The Beholder' or something, and then the crowd's expecting James [Hetfield, METALLICA frontman] to come out and sing, and it's, like, 'Man, this ain't working.' They were feeling like it was a prelude moment, and I started thinking, 'We've gotta do something different.' So Kirk came out this one night, and he started playing that song by CHIC ['Le Freak'], and it totally caught me off guard.

And I'm, like, 'Oh, damn.

Okay, I see where he's going.' He's walking out to the front of the snake pit playing this funk jam.

He got me the first night, 'cause I didn't exactly know the bass line, so I improvised it.

And then the second night, I got it," said Trujillo.

The band has been performing a range of songs from various genres and decades, including country, flamenco, and even Johnny Hallyday in Paris.

Not every artist that has been spotlighted in the "doodle" has been flattered by the performances.

Former CELTIC FROST frontman Tom Gabriel Fischer was not impressed with the rendition of the group's "The Usurper," calling it a "butchering.""
