BRITALLICA - The Underworld
BRITALLICA

BRITALLICA

Britallica are the Britney Spears metal tribute you never knew you needed. Formed in London in 2025 and taking the princess of pop’s biggest bangers straight into the mosh pit.

Expect monster riffs, thunderous drums, filthy basslines, soaring vocals, and a set packed with reimagined Britney classics from “…Baby One More Time” to “Toxic”, “Oops!... I Did It Again”, and beyond.

It’s pop nostalgia with a heavy metal heart: loud, ridiculous, glamorous, and guaranteed to get a crowd singing, headbanging, and questioning everything they thought they knew about 2000s pop. Britney. But make it metal.

Its Britallica Bitch!
