Sewell is best known for his vocals on Kygo's single "Firestone" and his number one hit single "Start Again". Growing up in Brisbane, Sewell started pursuing a music career from a young age, sending around demos since he was 8 years old. Sewell is the brother of singer-songwriter Grace, who is best known for her 2015 cover of "You Don't Own Me".

At the age of 18, Sewell moved to the UK and maxed out a credit card to record a demo. After moving to Los Angeles, he started working on his solo project. Several people have been a part of creating the new music including Jamie Hartman (Christina Aguilera, Joss Stone), Sam Hollander (Train, One Direction), and Eric Rosse (Sara Bareilles, Gavin DeGraw).
