I was inspired a lot more with this record with stripping things back and making it a lot more emotional. I didn't want to do a concept album, I always like it when I can write from a diary in a way. It's quite an emotional album. It's got elements from the first one, but it's definitely not as produced. The tracks feel a lot more vocal [with] piano and strings. It's still cinematic in ways but I'm a lot more honest on this record this time around, which is quite a scary thing to be.

Eight days later, on 29 January, she posted a black and white photograph of herself standing with two guys in a studio[4]. The next day, she tweeted about how she couldn't stop smiling about the album.[5].
On 12 June, she tweeted a video of herself in the studio with a choir of children[7]. On June 17, she posted a picture of herself surrounded by keyboards[8]. The next day, she tweeted a picture of herself with a tambourine[9].
On 1 July, she tweeted a picture of herself eating Nando's in the studio[10]. On 3 July, she announced that she was finally deciding on the album's track listing[11]. From 15 to 16 July, various Twitter accounts were sent postcards containing titles of some of the album's tracks[12][13][14][15].
