"Doom Days is easily the group's most cohesive album yet, but as they tighten their focus, they also expand their sound. Alongside quintessentially heartfelt Bastille songs like "Another Place" are tracks such as "4AM," which moves from a cozy acoustic singalong to brass and beats with the seamless flow of their mixtapes, and "Million Pieces," which sets Doom Days' escapist heights to rhythms that evoke '90s garage. On "Joy," the band draws on the power of a gospel choir to give the album a happy ending that feels well-earned, even if it's only temporary. This need to seize the moment has been one of Bastille's main messages since "Pompeii," and with Doom Days, they prove they can deliver it in increasingly eloquent and relatable ways".
