Frank Black has revealed he was unhappy with the way the Pixies' recent documentary was made.

The reformed band were filmed on their 2004 tour, and the resulting production was shown at the Edinburgh Film Festival on Tuesday. Black branded the filmmakers "naïve", claiming they did not know their subject.

"(They) were naïve, like a lot of people who don't understand how rock bands are when they go on tour," he told The Guardian. "They'd roll into the hotel every morning and say, 'So what are you guys going to do today? Ooh, are you going to go buy some ice cream?' I guess they expected us to be like the Monkees, always up to mischief. But we're boring, you know."

He also criticised the lack of footage of bassist Kim Deal, who asked to be cut from many scenes: "It made her look like she was hardly there, clutching her beer and chain-smoking cigarettes. It made it look as if we had just scooped her out of the gutter."
