No, Rosegarden Funeral Party is not a goth band, because they play Alternative/Pop Rock/Post-Punk, 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 "Fear of Feeling Nothing", "Chaos", and "Self Analysis".

If you want to dive into the goth music scene, some of the bands that might appeal to you if you enjoy Rosegarden Funeral Party are Siouxsie And The Banshees and Skeletal Family.
