The band’s singer Alex Trimble collapsed at Seattle Airport in 2014 as they spiralled out of control.
Alex explained: “We were very lucky, we kind of caught it before it was too late.
“Things were going so bad that there was a chance that some of us could’ve ended up dead if we had kept going, because it’s all the rock ’n’ roll cliches, you know: you get involved with the booze and the drugs and it turns into addiction and you’re kind of numb to everything that’s going on around you, because everything’s moving so fast and you’re having success.
“And you’re afraid to say no to all of these offers that are coming in next for you, because you don’t wanna lose people’s attention.”
Eventually Alex told the band he couldn’t continue and they took a year out from music.
He explained: “We had to put the brakes on and step back, and we’re a lot better for it now… we look after ourselves, we look after our relationships.
“And I would like to hope we’d see the signs if anything like that was happening again, but it’s such an easy trap to fall into.
“But the truth is that a lot of it is having to do things that you don’t really wanna do and it takes its toll.”
