The Fall of Hearts is the tenth studio album by Swedish heavy metal band Katatonia.

[5] Moilanen replaced the band's prior drummer of fifteen years Daniel Liljekvist, who left in 2014 to focus on family and pursue a more conventional career outside of music.

[7] Despite lineup changes, the album was still primarily written by founding members Jonas Renkse and Anders Nyström.

[12] Conversely, Moilanen had joined earlier, and had a larger role in shaping the album's content, with Renkse and Nystrom frequently discussing ideas with him.

[12] Songs were often changed throughout the process, with Nystrom noting that many demos were vastly different from final studio recordings.

[1][2] Loudwire noted the similarity of the track "Serein" to 1980's new wave music such as The Cure, due to its "gentle strumming and a soft lead... Jonas Renkse’s soothing, multi-tracked voice... a slightly uptempo rhythm [...] uplifting and pop-inflected [...] gorgeous, understated lead work textures.

AllMusic reviewer Thom Jurek praised the band for moving into an even more progressive direction, stating, "Their lyrics remain steeped in themes of loss, alienation, desolation, and the desire for transcendence, but their melodies are more labyrinthine, less straight-ahead, and conversely, contain more earworm hooks, making them more accessible to a wider prog rock audience than ever before.
