Cousins Jonathan Capeci and Joey Beretta grew up together around Philadelphia, Pennsylvania. Throughout their childhood and teenage years, they played in a number of bands together, but as they reached college, they dropped out and relocated to Nashville to pursue their project at the time, Dinner And A Suit. As that project dissolved, Capeci and Beretta regrouped with friends Stephen Cunsolo and Nicholas Sainato to form Nightly. The project lacked momentum until they signed with Interscope Records in July 2016 and began work on their debut EP.
In August 2019, the band announced that they had signed a new record deal with BMG. In the notes app screenshots they shared on social media, they also explained how challenging the past year was and that they needed to postpone their upcoming tour.
Nightly released their debut album, night, love you., on October 16, 2020.
