5 Seconds of summer
5 Seconds of Summer (5SOS) are an Australian punk/rock band formed in Sydney in 2011. The band consists of Luke Hemmings , Michael Clifford , Calum Hood, and Ashton Irwin. Luke started making YouTube videos of him covering songs and from there he called Michael, Calum, and Ashton to play with him. They practiced regularly in a garage and that's when they decided to call themselves 5 Seconds of Summer. From all the YouTube videos they were posting together, they gained a small family of fans. It led to catching the eye of One Direction member, Louis Tomlinson, who then took it upon himself to arrange 5SOS to be the opening act for One direction on their Take Me Home Tour.
