No, Samhain is not a goth band, because they play Horrok Punk/Heavy Metal, 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 "In My Grip" and "To Walk the Night".

If you want to dive into the goth music scene, some of the bands that might appeal to you if you enjoy Samhain are 45 Grave, Christian Death, and Screaming Dead.
