In early 2014, Nick Turner and Jake Jones left the band and were replaced by Nick Rossi and Tyler Burgess, respectively. New Years Day embarked on a European tour with Escape the Fate and Glamour of the Kill in the following months. The band graciously parted ways with their previous label, Century Media Records and released of the first single off their upcoming "Epidemic EP" titled ""Other Side"" through Grey Area Records on November 18, 2014. When asked about the new EP, Costello commented in an Alternative Press interview, "We've taken what we have experienced in the past year and a half and poured it all into these new songs... It's something we know everyone can relate to on their own level. The world can infect us with its negativity, and it's okay to struggle with it. That's truly what "Epidemic" is about. Owning the diseased parts of us and turning it into a strength."
