Even when 5 Seconds of Summer are taking a break from the hustle and bustle of their very, very busy lives...they're still doing stuff. 

In the last month we've been gifted the fan-assisted "Jet Black Heart" video. The Aussie lads landed a controversial Rolling Stone cover story. And on Monday night, 5SOS performed their Sounds Good Feels Good single, "Hey Everybody!" It's a stripped-down performance, possibly the first time we've heard the track done acoustically. Watch it above.

It might be a youth anthem but it totally works with the guys, somber and sensitive, sitting on stage stools.
