Paolo Nutini was just 20 when his debut album "These Streets' stormed into the charts with tracks like New Shoes, Jenny don't be Hasty and Last Request.
After a successful second release, the Scottish musician took a break from the limelight. But four years on and he's back with 'Caustic Love' - an album one critic has called perfect.
Nutini joined BBC Breakfast to talk about his music and why he loves his holey jumper.
