Guitarist Joel Peat said of the album: "We're all so excited to release our debut album, we've been building up to it for the past four years, and the album's title for us is special, because it is the first place that we played together as a band. Going out on tour to support the album is amazing too. Doing shows in our Hometowns feels like the perfect way to celebrate. Performing live is what we love the most, so to be able to play our biggest venues to date in the cities where we grew up is very special." Lawson have cited many inspirations for their debut album, including John Mayer and Taylor Swift. The album's track listing was confirmed by the band via their official website on 24 September 2012.
