Letters
The Sun previewed five tracks from the album:
'Run For Your Life' is described as containing a collection of guitar riffs and string sections, "reminiscent of Snow Patrol's biggest hits".
Cardle explained that 'Starlight' is "a depressing happy song about the insignificance of everything", while 'Amazing' is "about finding someone when you've got no-one".
The 28-year-old co-wrote 'All For Nothing' with Adele collaborator Eg White. Cardle said: "I recorded it after a couple of cups of tea and a few cigarettes so it's quite raw."
Title track 'Letters' is described as sounding reminiscent to Coldplay's 'Fix You', with Cardle employing a "Chris Martin-styled falsetto". Lyrics in the chorus include: "Send a message to my heart."
