KT Tunstall's explains why her new album was recorded in two halves

Scottish singer KT Tunstall has been talking about recording her fourth album in Arizona.

She first came to the public's attention in 2004, when she was asked to play on Later With Jools Holland because of a last minute cancellation.

Armed with just a loop pedal, a guitar and a tambourine, her performance led to a string of albums and awards.

She told BBC Breakfast why her new album is made up of two different halves and how it was affected by the death of her father.
