5 Seconds of Summer get hands-on with ticket sales

The rising pop-rock band 5 Seconds of Summer gave its feverish female fans the surprise of a lifetime by personally selling tickets on Saturday morning for an upcoming concert in Inglewood, California.

Many fans, including 13-year-old Trina Umana, camped out overnight at The Forum to get seats for the Australian group’s first U.S. headlining concert on Nov. 15.

“I can’t speak right now. I’m too overwhelmed,” she sobbed after purchasing her tickets from guitarist Michael Clifford, 18.

Before heading into the box office, drummer Ashton Irwin, 20, said his only concern was the group’s math skills.

“We might lose track of a lot of coins and stuff like that. But we’ll work it out. We’ll get through it,” Irwin joked.

Maria Gomez certainly wasn’t paying attention to the numbers.

“All I could think was: ‘Oh my God. I don’t know what to do. Don’t embarrass yourself!’” said the 15-year-old fan from Anaheim, California. “None of us thought any of this would happen.” The quartet, which also includes lead vocalist and guitarist Luke Hemmings, 18, and bassist Calum Hood, 18, can relate to the fandom.

“We’re more awkward than anything,” said Irwin of meeting artists he admires like Fall Out Boy bassist Pete Wentz. “But inside, when they leave, we sort of squeal.”

Green Day, Blink-182 and Imagine Dragons also top their list of musical influences.

Saturday’s crowd was treated to a live, outdoor performance of their hits She Looks So Perfect and Amnesia.

5 Seconds of Summer is mirroring the seemingly instant success One Direction achieved when that group hit the U.S. music scene in 2012. 5 Seconds of Summer is currently opening for One Direction on the Where We Are tour.

5 Seconds of Summer will play to roughly 17,500 fans when it headlines at The Forum, an impressive feat for an emerging act. The group’s self-titled debut album came out last week. Billboard predicts it will debut at No. 1.
