5 Seconds of Summer, simply known as 5SOS, came from Australia to rock the world. Now that success has been inevitable for them, frontman and guitarist Luke Hemmings recalled their humble beginnings and revealed their biggest secret to success.

“They’re four dudes from a small town who stuck to their guns and became huge. That’s what stuck with me the most,” he revealed during a chat with Young Post, as Sugar Scape quoted. The Aussie lad added that their victorious career as a rock group was never “expected.”

“When we started going on tour in Sydney we never expected we’d be able to play at all these places around the world,” he explained. “We were very confident in ourselves and knew we had something special, but I don’t think we knew how big we could make it. It blows my mind.”

Hemmings, along with Michael Clifford, Calum Hood and Ashton Irwin already released two full-length albums. The rock quartet started to invade the rock and rock industry with their first self-titled LP “5 Seconds of Summer” which was out in 2014.

Then, the group had their first major concert dubbed as “Rock Out With Your Socks Out” tour that was a success. After that, blessings smoothly flow on their career as they released the sophomore material “Sounds Good Feels Good,” and is currently invading the world with their 8-month long “Sounds Live Feels Live” concert that is currently happening in Kuala Lumpur.

The boys wowed the crowd when they held the event in Kuala Lumpur, Malaysia on March 2, notes Movie News Guide. The concert began at 8:25 pm but despite being late, fans still screamed and sang along the punk rock band.

The bassist thanked the fans by saying that, “I’m not just saying this, but you’re the best crowd so far,” Star 2 reported “You guys could possibly be the most attractive crowd,” Clifford added.
