5 Seconds of Summer fit the boy band mold: a quartet of young men with a feverish female fan base touring with British megastars One Direction. But the Australian pop-rock group identifies more with Pete Wentz than Harry Styles.
"I (grew up) watching, you know, live rock 'n' roll bands and I wanted to be like Tre Cool ... from Green Day," said 5SOS drummer Ashton Irwin, 20. "To be called a boy band coming from those roots and writing our own songs and starting in the garage, it's just, I don't think it's the correct term for us."
5 Seconds of SummerWhat: Performs with One Direction's Where We Are Tour
When: 7 p.m. Friday and Saturday, Aug. 29-30
Where: Soldier Field, 1410 Museum Campus Drive, Chicago
Tickets: Start at $59.50
The group's first full-length, self-titled album debuted at No. 1 on Billboard's 200 albums chart recently. 5SOS' debut single, "She Looks So Perfect," became a Top 40 hit and the follow-up, "Amnesia," did as well.
Irwin said the "high-energy rock album" was inspired by guitar bands of the '90s and early 2000s, including Blink-182 and Jimmy Eat World, as well as contemporary performers such as Imagine Dragons.
Despite that, One Direction has had some influence on 5SOS.
"We've become comfortable. I think we're just like really very used to having each other on the same tour," said Irwin. "They've had us on their tour for like two years now."
The Canadian and U.S. leg of One Direction's "Where We Are" stadium tour kicked off in Toronto, where 5SOS opened. The tour plays two Chicago shows, Aug. 29 and 30, at Soldier Field.
"The way they treat their crew and stuff like that, it's a real family-type environment and really we look up to that," Irwin said.
The rising band is also performing for larger audiences: 5SOS announced they would headline an arena tour next year.
Despite the group's early success, social media stardom and devoted fan following, the band -- which includes vocalist Luke Hemmings, guitarist Michael Clifford and bassist Calum Hood -- is taking their newfound fame in stride.
"I don't see us as having any fame factor," said Hemmings. "We're just dudes in a band that plays some stuff."
They also co-write most of their music that, like the breakup song "Amnesia," focuses on love -- or lust -- and heartache.
"It feels nice to write about girls because it gets it off your chest," said Clifford. "It's good."
But there's no time for love.
"(We're) married to the band, we always say," Hood said.
