5 Seconds of Summer is a boy band from Sydney, Australia that's composed of Luke Hemmings, Michael Clifford, Calum Hood and Ashton Irwin. Formed in 2011, when Hemmings and Clifford began earning internet attention by covering popular songs on Youtube, the group has captured a national fan base with its debut EP, Unplugged, and an accessible pop punk sound. The band tapped into the international following of fellow boy band One Direction when the London-based group posted a 5 Seconds of Summer video on its official site. The four-piece group would go on to join One Direction on a world tour, distinguishing itself from other boy bands by playing their own instruments.
