New Zealand has a major noise complaint on its hands: Siren Kings.

Since 2010, the self-proclaimed Siren Kings, a community of music-loving creatives that happens to be the world’s loudest subculture, have been terrorizing New Zealand suburbs with blaring sirens and, well, power ballads.

If you’re a Céline Dion or Mariah Carey fan, you might actually be on board with this group. (Although maybe not at 3 a.m., which is when they’re most active.)

They claim to channel noise as a form of self-expression and community-building. However, with their use of tsunami-warning sirens and max-volume car stereos, the Siren Kings take things a bit too far—according to sleepless neighbors, at least.

Local investigators from the Department of Information interviewed exhausted residents who expressed their frustrations about being woken up by blaring sirens at 3 a.m. They also met with the Siren Kings to understand their mission and blatant desire to disturb their New Zealand suburbs in an oddly wholesome manner.
