Read this: The story of pop-punk in 16 songs
Speaking to Kerrang! last year for a track-by-track guide to Wake Up, Sunshine, Alex explained of Monsters: "This was done in Palm Springs, in the later part of the process. We knew once we’d written it that we had something special; there was an energy that felt like it was going to be one of the standout songs on the record. Andrew [Goldstein, songwriter] had been working with blackbear on his new music, and as we were listening back to everything, he spoke up and said, 'It would be really cool if we sent this to blackbear!’ We had never thought of that before, but he was really into it, and he sent back this thing to Andrew saying, 'This is kind of the headspace I’m in at the moment anyway, so I already feel like I could write something for this.’ It really elevated the song, and took it to this new, refreshing place that we had never properly explored before. We’ve never really collaborated with someone in rap or hip-hop, and this brought a lot more energy to the song. It was a fun one to do!”
