No, Holy Cow is not a goth band, because they play Hard/Punk Rock, Experimental, 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 "Ichorus Pus" and "Noises".

If you want to dive into the goth music scene, some of the bands that might appeal to you if you enjoy Holy Cow are Bauhaus and Turkey Bones & The Wild Dogs.
