Refrain began as a jam session between school friends who discovered they played instruments. They chose the name Refrain after coming across the musical term online and liking how it stood out. Their music is inspired by bands like Rage Against the Machine and Red Hot Chili Peppers, while lyrics draw from solo artists like Danny Jones of McFly. The best gig they played was their second headlining show at the O2 Arena, where they surprised fans by going topless. The band advises aspiring musicians to work hard at finding a style they enjoy.
