Filmmaker Vincent Moon has launched an astonishing attack against Arcade Fire.

Moon was responsible for the documentary Miroir Noir, which saw him spend a prolonged spell with the Montreal-based band in 2008.

In an interview with Eye Weekly, the director said he did not enjoy his experience with the group, and labelled their leaders and management as “not good people”.

“The way they deal with their business is really disgusting for me. The way they deal with things is awful,” he said.

"Their management are awful, awful people, and I know what I'm talking about. I have some really terrible stories with them."

Moon added that he was frustrated when people described Arcade Fire as an “indie band”.

"What I hate about the band now is that people call them an indie band and they're not an indie band, they are a mainstream band,” he said.

"Maybe they're on an indie label but that doesn't mean anything. Those guys are just making things on a very big level, a very mainstream way of thinking."

Miroir Noir offered a behind-the-scenes look at Arcade Fire as they put together their 2007 album 'Neon Bible' and set off on tour.
