5 Seconds of Summer

5 Seconds of Summer, the not-so-little pop-punk band from Sydney, Australia, had another huge milestone in their music careers today.

One Direction is coming to Chicago this August with their buddies 5 Seconds of Summer. Who else is gonna be there? Well you could.

5 Seconds of Summer may sound completely pop with their hit 'She Looks So Perfect,' but don't ever doubt that these guys can rock.

5 Seconds of Summer released a hilarious behind-the-scenes video for their latest comic book-themed music video ‘Don’t Stop,’ recorded from the perspectives of their superhero alter egos.

You wouldn’t think Liam Payne would be jealous of much, considering, y'know, he’s a member of wildly successful One Direction and holds the title of one of the wealthiest young musicians in all of Britain. But that’s not so, he shared, and his green eye is directed towards none other than 5 Seconds of Summer.

We'll admit it -- we got a little giddy when we saw 5 Seconds of Summer walking the 2014 Billboard Music Awards red carpet. It may be a major U.S. appearance for the boys, but they looked totally at ease working it for the cameras.

If you haven't heard of 5 Seconds of Summer yet, you might want to want to spend a few minutes getting to know these guys.
