Pupil Slicer is a London-based mathcore and extreme metal trio known for their angular, complex, and often chaotic music, influenced by bands like The Dillinger Escape Plan. Formed by Kate Davies (vocals, guitar), Josh Andrews (drums), and Luke Fabian (bass), the band uses lyrical themes that explore deeply personal experiences, social issues, and science fiction concepts, as seen in their albums Mirrors (2021) and Blossom (2023). They are known for their energetic live performances and have released three full-length albums through Prosthetic Records.
