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.
