METALLICA: Pro-Shot Video Of 'Spit Out The Bone' Performance From Cologne

Professionally filmed video footage of METALLICA performing the song "Spit Out The Bone" on June 13 at RheinEnergieStadion in Cologne, Germany can be seen below.

METALLICA played "Spit Out The Bone" live for the first time ever in October 2017 at The O2 Arena in London, England. The track is taken from METALLICA's latest album, "Hardwired… To Self-Destruct", which came out in November 2016. Frontman James Hetfield told Colombian radio station Radioacktiva that the songtitle was inspired by how people are connected to each other through mobile devices and how everyone is becoming more dependent on technology. "[It] is getting rid of the human flesh part," he said. "And machinery is so much more efficient. And ourselves as people, [we're] very… I don't know… We want things quicker, we want the convenience of technology, but at what point is convenience leaning into dependency, and we need it, or else we don't know what to do."

The original version of "Spit Out The Bone" was close to 10 minutes long before METALLICA realized it needed to be trimmed, making it leaner and thinner, more concise. Drummer Lars Ulrich told Rolling Stone: "That was just an adventure, man. I have versions of that song that are two to three minutes longer. We just kept going and going and going. That was also the first song where we went, 'Wait a minute. Is there too much of a good thing here?' And then we started peeling it back.

"It was one of those where you just keep going to different universes and different modes and areas because it was super fun," he continued. "It was like this journey. Old-school MERCYFUL FATE–type stuff was kind of the inspiration for that."

Hetfield spoke in more detail about the song's meaning during an interview with METALLICA's fan-club magazine So What!

"This is a little different, just the wonder and fear of, again, what's happening to man," he said. "Without future tripping too much, just the possibilities of 'Terminator', stuff like that, you know. We're wearing smart watches, things are getting closer and closer to just being in us.

"Why would I not have the Internet in my head all the time? Why do I have to worry with all these 'emotions' and stuff? Falling in love and getting your heart broken? That doesn't do anybody good. You know, the heart and blood? It's in the way of efficiency! We could be a much more efficient race if we just allow computers to help us.

"And yeah, they are helping us, but how far does that go? All of that craziness. So 'Spit Out the Bone' is that your bones aren't needed. They break!"

Hetfield reportedly lifted the title from legendary U.K. punk band GBH's 1982 track about the 1972 Andes flight disaster titled "Passenger On The Menu". James said: "Yeah, thank you, GBH, for the 'spit out the bone' line. I know their song was a little different. Their song was about the Donner Party and cannibalism."

METALLICA's "WorldWired" tour has played more than 130 shows across the world since its 2016 kick-off.

Last November, Ulrich told The Mercury News that the trek could last through early 2020.
