5 Seconds of Summer.

Three eight ago , I discovered a group that were friends of One Direction, called 5 Seconds of summer.
It is an Australian pop rock band. Formed in Sydney in 2011, the band consists of Luke Hemmings , Michael Clifford , Calum Hood , and Ashton Irwin .

5 Seconds of Summer began in December 2011 when Luke Hemmings, Michael Clifford and Calum Hood, who all attended the same school , joined together and started posting videos of covers of popular songs to YouTube.

When Louis Tomlinson from the  band One Direction posted the link to their YouTube video of their song Gotta Get Out, stating that he'd been a fan of 5 Seconds of Summer.

On 21 November 2013, the band announced that they had signed to Capitol Records. 5 Seconds of Summer are currently working on their debut album.
