Muse have been employing drones to fly overhead on their current tour. Unfortunately, one of those drones malfunctioned and crashed into the crowd at the band's gig in London last night (April 14).

Last year, the English rockers returned with Drones, a concept album frontman Matt Bellamy called a metaphor for "psychopaths which enable psychopathic behavior with no recourse." To drive that idea home, the band has been using actual drones at their concerts, but during their third show of a four-night residency at the O2 Arena, a blimp-shaped drone of some size veered off course and quite slowly dove toward the audience. The band’s crew scrambled to get it down and remove it from the venue. No injuries have been reported. Some fans in attendance caught the moment on film, which you can see at the bottom of the page (via NME).

When announcing the band’s tour, Bellamy was enthusiastic about the prospect of offering fans a very literal visual for their new album, but he admitted there would be obstacles they would have to cross. “Drones are obviously an interesting thing to try to bring into the live show, so we’re going to try and do that,” the singer said. “There’s going to be some difficulty with red tape of health and safety about flying things over, but the general idea is that as the tour starts that we’ll be using flying objects.”

In fact, Muse’s O2 show wasn’t the first time one of the band’s drones short-circuited. It also happened at the their Detroit concert.
