5 Seconds of Summer are not a boy band, and their live show should be proof enough. The four-piece, Australian pop-punk band packed out the PNC Bank Arts Center all the way into the lawn on Sunday night and fans of all ages could not stop screaming. With loud guitars and impressive production, 5SOS kept the crowd on their feet for hours – singing along to every lyric. Opening up for the band was Japan’s One OK Rock and 5SOS’ prodigies, Hey Violet. Check out some photos from the show!
