Paul Epworth has revealed that Adele recorded her vocals for James Bond theme tune 'Skyfall' in just ten minutes.
The producer explained that the award-winning singer immediately loved the track, and "had the lyrics ready in her head when she drove over [to the studio]".
"Within 10 minutes, she put down most of the vocals," said Epworth. "It was the most absurd thing. She's fast, but it was really quite phenomenal."
Epworth also told Hollywood.com that he was surprised by Adele's sultry delivery in the song's opening bars.
"She has an old soul," he said. "She never really mentioned she could sing the [Shirley] Bassey-esque slurs that she does in the opening.
"She's actually a very controlled vocalist. She has a lot of finesse and skill. She's not just a powerhouse - it's a lot of careful technique. That's why she's an amazing vocalist. It's all control."
