John Cale (a founding member of Velvet Underground and musicmaker) teamed up with Australian speculative architect Liam Young to create LOOP 60Hz: Transmissions from the Drone Orchestra, a collaboration between music and motion, a kinetic illustration of "unholy noises" (Cale's words) as much as it is a sonic expansion of the movements of drones.

Why drones? Well, why not drones? They're seen as quite militaristic things, of course, that's natural, but in this performance, shown mid-September this year at the Barbican, they're dressed in costumes; some look absolutely mental, some just look plain silly, but that's all to expunge the idea of the faceless fear-inducing drones from the news and instead embed the idea that that they can be fun, playful, as innocuous and personable as mobile phones.

This came only after two years of searching for the right venue. Drones like these, robust flying machines with vicious propellors and the propensity for being used for scaring pigeons, medical supply delivery, and other outdoors things, aren't meant to be flown indoors.

"These propellers are gonna take someone's head off if you let them," explains Liam Young. "It required someone with some vision and some bravery to let us attempt it. And it really is the first time that these things have been flown above the heads of an audience."

The documentary, made by the Creators Project, explores the dynamics of the drones-turned-characters, the way they move to music, and what the music itself can conjure for the audience. John Cale's statement is self-explanatory: "Drone: a bleak tapestry of unholy noises, searing into the listeners ears and – with any luck – transporting them to a place they'll not want to leave for long while"
