Apocalypse & Chill

The album focuses on themes such as the climate crisis and the way people react to it, with Martijn Westerholt stating:

It's really the contrast that you see when you turn on the TV, You see Australia in flames and then you turn to Instagram and see people with awesome pictures of their garden or themselves. The perfect life. The same world but such a contrast. It's what comes across on the album in the music and in the lyrics. We are a band of contrast with the heavy guitars but with some pop and synth elements so it all comes back to that.

Writing for Kerrang!, Steve Beebee stated that it was Delain's best album to date and rated it a 4/5.

Metal Injection gave the album an 8/10, stating that "symphonic metal typically sticks to familiar ground, with only marginal variation and experimentation from time to time, and Delain undoubtedly still do it better than most of their peers."

Blabbermouth also gave the album an 8/10, adding that "Delain have upped their game in every department, eschewing cynical acts of musical shark-jumping in favor of aiming for the best and most powerful manifestation of a simple idea."
