"I think all artists change their sound because they’re not satisfied in the art they’re making. We started out, very angsty, trying to get out of the hometown, and people called us a boy band, but we played pop punk music, it was written like that. As you get older, your music taste becomes more diverse and you get a bit smarter about it. You just bring in those kind of elements and you want to remain happy in what you’re making."
