5 Seconds of Summer (commonly abbreviated as 5SOS) are an Australian rock band from Sydney that formed in 2011. The group were originally YouTube celebrities, posting videos of themselves covering songs from various artists during 2011 and early 2012. They rose to international fame while touring with One Direction on the Take Me Home Tour.
The group have been referred to as a pop punk band in the media, though the members reject this description, claiming that they desire to play more music than just pop punk.
In early 2014, the band released “She Looks So Perfect” worldwide as its debut single, which topped the charts in Australia, New Zealand, Ireland and the United Kingdom.
