"We have a huge rig and pyrotechnics so often it's the case of fitting all that into the venue," Ashba tells Yahoo! 7 News. "Our number one priority is to make the shows safe."

Ashba says he understands why fans have resorted to bottling the stage or venting their anger on social media. "That kills us as a band because we're not doing any of this on purpose," he explains. "Our main goal is to go and give the fans a show they will never forget and we understand how expensive tickets are. We take that into account and when we do hit the stage it's almost impossible to get us off."
