Singer/guitarist Carlos Garcia commented on the forthcoming album: "We've just wrapped up the making of our new album with Paul Miner. We're super stoked on the finished product, and we hope everyone will feel the same! Paul was amazing to work with, he was very encouraging and super patient with us, and we're eternally grateful for that. And of course, he knows his way around the console. This is honestly the first album we've done that is an accurate representation of Antagonist's live sound, and it definitely showcases a more refined, aggressive sound. We're taking it back to the old school!"

Garcia also commented on the overall sound of "World In Decline;" "'Exist' had a hopeful message of working together as humans towards a better future. The new album is about the realization that things will always be f**ked up, people will always be selfish, and this world is going to end at any minute, and we have nobody to blame but ourselves. People grow older and figure out that life doesn't get any easier and that our own selfishness, carelessness, and ignorance are at the core of our demise. So right now, that's where our heads are at, which will in turn no doubt lead to a much more aggressive and angry album. "
