5 Seconds of Summer Details

5 Seconds of Summer, often shortened to 5SOS, are an Australian pop rock band from Sydney, New South Wales, formed in 2011. The group consists of lead vocalist and rhythm guitarist Luke Hemmings, lead guitarist Michael Clifford, bassist Calum Hood, and drummer Ashton Irwin. Originally beginning their career as YouTube celebrities, they rose to international fame while touring with English-Irish boy band One Direction on their Take Me Home Tour. They have since released four studio albums and headlined multiple world tours.

In early 2014, the band released "She Looks So Perfect" as their debut single, which topped the charts in Australia, New Zealand, Ireland and the United Kingdom. Their self-titled debut album was released in June 2014, peaking at number one in 11 countries. The band embarked on their first headlining arena world tour, the Rock Out with Your Socks Out World Tour, to support the album. The band released their second album Sounds Good Feels Good in October 2015, topping the charts in 8 countries and later embarked on the sold out stadium and arena Sounds Live Feels Live World Tour to support the album.

The band released their third album Youngblood on 15 June 2018. It was a commercial success and became their third number one album in their home country. In the US, 5 Seconds of Summer became the first Australian act to achieve three chart-toppers on the Billboard 200 album chart. They also became the first band (not vocal group) to have their first three full-length albums debut at the top in the US. Further, the band became the first homegrown act in 13 years to top ARIA year-end tally and are the second longest stint at number one atop the ARIA chart in history. Throughout 2018, the band embarked on the promotional worldwide 5SOS III Tour, which sold out within three minutes, and the Meet You There World Tour to support the album.

On 27 March 2020, the band released their fourth studio album Calm. The album was a commercial success, receiving positive reviews from critics who praised the band's artistic growth and maturity. The album charted in more than 25 countries on several charts, peaked in the 10 top on 17 charts and debuted atop the charts at number one in Australia, the UK and Scotland. In the US, due to an alleged shipping error, approximately 15,000 copies of the album were released early, which resulted in Calm debuting a week early on the Billboard 200 chart. Had the shipping error not occurred, Calm would have debuted at number one in the US, earning the band's fourth consecutive number one in the country. Despite the shipping error, the album peaked at number two in the US, earning the band their fifth top 10 album on the Billboard 200 chart. With Calm earning the band their fourth consecutive number one in their home country, 5 Seconds of Summer became the second Australian band in history to have their first four full-length studio albums debut at number one on the ARIA albums chart. The band is set to embark on their No Shame World Tour in 2021.

All singles from the band's four studio albums, as well as all four albums, have charted in a substantial number of countries, received multiple official sale certifications, and have been featured in a large amount of weekly and year-end charts, as well as making an appearance on decade-end charts. 5 Seconds of Summer were named on Billboard's Top Artists of the 2010's Chart, which lists the most popular and successful artists of the 2010-2019 decade. As of mid-2020, the band's estimated net worth is approximately $81 million (AUD).
