"[We've been getting inspired by] life, really. It's not one specific instance or record or book or anything. We're constantly taking in new music — that's what we're passionate about — but I think life has given us a lot to say, and I'm really excited," Williams said. "Josh has been writing really cool riffs and really cool music that I can't wait to write over. Lyrically, I think it's going to be a very different record — we've learned a lot about relationships and friendships and life in general, and I'm stoked because I don't really know what I'm going to say about it, but I've got a lot that I want to get out."
