A host of Paris gigs were scrapped in the days following the attacks on the city, which included a massacre at an Eagles of Death Metal concert at the Bataclan theatre.

U2, Foo Fighters, Brantley Gilbert, Marilyn Manson, Motorhead, the Deftones and Prince all cancelled or postponed performances in France, but Cleveland rapper Machine Gun Kelly refused to axe his La MAChine du Moulin Rouge gig at the weekend.

"Obviously, there's an initial feeling of hesitation," he tells Billboard, "but as a voice of the young people who were also victims of that attack, and the victims of a lot of things going on with how society is treating our generation, I just believed it was kind of like what we made music for in the first place, which was to spark change or inspire or create an escape.

"When I'm on stage and those people are in the venue for that hour and a half while we're on stage, it's like they're free of all the realities outside of those walls. So I felt like it was sort of our duty to go and give those people an escape in such a tragic time."

But the ghosts of the Bataclan atrocities were weighing heavily on everyone's minds as the rap star hit the stage.

"Stagehands had walked past us and everyone was saying stuff like, 'Be safe'," he recalls. "Kind of paranoid vibes were going around the building more and more right before showtime. So it kind of hit me right before I went on stage."

However, there was a magical moment during the show that made the risk worthwhile: "I was playing my song A Little More and we break the song down; I'm playing the guitar on it and we kind of play it like a stripped down, acoustic version. And while that was happening, they (fans) just started singing their national anthem. Like, the whole crowd, singing the loudest I'd heard them all night.

"It was so appropriate with the song selection and everything that song is about, and it was like, as soon as it was over they busted out into this group rendition of their national anthem. And it was one of those moments when I put my glass in the air and we had a toast and a moment of silence."
