The song is primarily about the anxiety - and also the excitement - one feels at the start of something new. We ask the age-old questions: Where is this going? Is this going to work out? What's in store for the future? How long will it take to feel truly at ease? Basically, when will the walls come down, if they come down at all? There are so many questions we torture ourselves with and this song tries to speak to that. Thin Air is also about my fear of flying - hence literally being in thin air and the sense of vulnerability that goes along with that. I wanted to utilise this theme in the metaphoric sense but in my case it's quite literal! The good news: my boyfriend and I are still together and doing very well and I'm not quite as anxious on airplanes these days.
