Before the release of their second albumColourmeinkindness, Basement announced a hiatus because of personal commitments. Guitarist Alex Henery later revealed it was due to vocalist Andrew Fisher wishing to become a certified teacher which required him to return to school for a period of a year and a half. Drummer James Fisher, Andrew's younger brother, was graduating from art school, and the rest of the members were working on their respective careers. Henery, meanwhile, was working as a videographer in Boston, Massachusetts for record label Run for Cover. In late January 2014, the group announced that they would be returning from their hiatus and would perform shows during the summer. The band recorded an EP, Further Sky, in secret before releasing it in July.
Production
In August 2014, Henery revealed the group was writing material for a new album. Although Henery was located in the US and the rest of the band was in the UK, they would send each other ideas. The group managed to have a few practice sessions before composing the album. Henry found it "a little tough", but the group managed to " it work". In early April 2015, the band posted they had begun recording with producer Sam Pura. Recording took place at Assault and Battery 2 in England, while mixing would later be done by Pura at the Panda Studios in California. Brian Gardener mastered the recordings. The album's sound has been described as alternative rock, compared to American bands such as Jimmy Eat World, Failure, and Soundgarden. Henery later named American band Autolux as "the biggest influence" on the record as "they just had energy and had that distortion, but still had really cool melodies."
