5 Seconds Of Summer

In a few short years, 5 Seconds of Summer evolved from a charming pop-punk band to one of the more formidable forces in rock and pop. Formed in Sydney, Australia, by college friends Luke Hemmings, Michael Clifford, Calum Hood, and Ashton Irwin, 5SOS first got a foothold in 2011 with a series of acoustic covers posted to YouTube—a path that helped them build their ravenous fan base from the ground up.
