As shown in this interview with John And Jacob right before they performed at Nashville Chapter's 2015 GRAMMY Block Party, the four on the left grew up together in Birmingham, Ala. They are bassist Jake Thrasher (Davidson's cousin), drummer Trevor Davis, and singer/songwriters Jacob Bryant and John Davidson. Jacob and John moved to Nashville in 2012, met Austin (on the right), and wrote "Done" with Band Perry and had "Be My Girl" placed on S.2 Ep.5 of the TV show "Nashville." The four from Birmingham also perform as The Brummies. "When people come to a festival, they want to have fun," said Bryant, "and that's exactly what we're doing."
