No, The Sere is not a goth artist, because they play Synthpop, while goth music consists of Gothic Rock and its derived genres, like Deathrock, Darkwave, Ethereal Wave, and Coldwave.

However, they do have a significant goth influence and even have some goth songs in their repertoire, like "Always the Cold Moon".

If you want to dive into the goth music scene, some of the bands that might appeal to you if you enjoy The Sere are Drab Majesty, Harsh Symmetry, and Twin Tribes.
