KT Tunstall has said leaving her husband is marked by a complete change in style halfway through her album.
The singer split from husband Luke, the drummer in her band, after her father died midway through recording her fourth album Invisible Empire // Crescent Moon.
Explaining her early recordings for the album before his death had been about having to make the final journey for someone between the place where they died and where they're laid to rest, KT said of her father: "Three months later, I'm carrying my dad's ashes in a backpack on a train to London."
She said the bereavement had given her the courage to leave her husband.
"So my personal life went crazy, there was a seismic shift in my life...," she said.
"By the time I went out for the second recording session in November, I felt like completely different person.
"Life had changed, and that's why there's a real noticeable difference between the two halves of this album.
"The first half is small-sounding and introverted, and then the second half goes widescreen. When I recorded that, it had been a few months since all that s*** had happened and I'd started to feel hopeful again. There was a rebirth going on."
