5SOS is an Australian pop band that formed in Sydney in 2011. The band consists of Luke Hemmings, lead vocalist and guitarist. Michael Clifford, guitarist and vocalist. Ahston Irwin, the bands drummer and vocalist. And, Calum Hood their bass guitar player and vocalist. The band was originally a Youtube hit, in which they got found and produced. The band ended up touring with One Direction on their Take me Home tour. Their most well known bands are Don't Stop, an EP in 2014, 5 Seconds of Summer in 2014, and LiveSOS, where it's them performing all of their songs, but live in 2014. They have many other songs, that not a lot of people know about, such as Daylight and Unpredictable. Their most popular songs are "She Looks so Perfect", "Amnesia", "Good Girls", and "Don't Stop". However my favorite 5SOS song is "Heartbreak Girl" because of it's catchy tune, and great beat/rhythm.
