Enigmatic singer Kate Bush has told the BBC she thought she would never finish Aerial, her first album in 12 years.
Bush said she became "fed up" making her latest record
"There were so many times I thought I wasn't going to have the energy to see it through," she told Radio 4's Front Row show. "I was so fed up making it."
In the interview, to be broadcast this Friday, the 47-year-old admits she is "horrible to work with".
She also reveals she found it hard to juggle her musical career with raising her seven-year-old son, Bertie.
"I felt my work could wait, whereas his growing up couldn't."
Listeners on Friday will hear Bush tell John Wilson she has not deliberately shunned the limelight since the release of her 1993 album, The Red Shoes.
"I am a private person, but I don't think I'm obsessively so," she said.
"It's more that I choose to try and have a normal a life as possible. I don't like to live in the glare of publicity."
Asked if she is a perfectionist in the studio, the singer replies: "I'm very opinionated.
"I'm so fussy and picky. What's good is that I know what I want. It's when you don't know what you want when you're in trouble."
Bush's new album will be released in the UK on 7 November and in the US one day later.
The first single from the record, King of the Mountain, is at number four in the UK singles chart.
