Bluegrass-country star Alison Krauss was forced to take a hiatus during the recording of her new album Paper Airplane after the stressful studio sessions made her ill.
The singer/songwriter re-teamed with her band Union Station last year (10) to lay down tracks for their first album in seven years.
But she worried so much about perfecting the record, she had to take a break from work because she was suffering agonising headaches and severe insomnia.
Krauss tells Britain's Live magazine, "I had to take a break from the new album because I was worrying over it so much that it gave me these killer headaches. That led to me finding it difficult to sleep, which would bring on worse pain and more worry - which wouldn't let me sleep. I got into a vicious circle."
