5 Seconds of Summer (also known as 5SOS) are an Australian pop rock/pop band with pop punk elements.

Formed in Sydney in 2011, the band consists of Luke Hemmings (lead vocals, guitar), Michael Clifford (guitar, vocals), Calum Hood (bass guitar, vocals) and Ashton Irwin (drums, vocals). The group were originally YouTube celebrities, posting videos of themselves covering songs from various artists in 2011. From there, they gained a small following in 2012 after posting a series of cover versions of popular songs onto YouTube, then rose to international fame when One Direction invited them on their Take Me Home Tour.

The group have been referred to as a boy band in the media. In February 2014, they released "She Looks So Perfect" as their debut worldwide release. It topped the charts in Australia, New Zealand, Ireland and the United Kingdom. Their self-titled debut studio album was released in June 2014, which peaked #1 in 11 countries.

A.K.A the most amazing group of four Aussie's to ever be put together, and exist on this Earth.

A boy band consisting of mediocre music playing. They're known best for ripping off guitar riffs and covering a really good band. They are evidence that God is abandoning us
