Ratzilla is a New York based instrumental progressive metal band drawing from modern fusion, stoner metal, old school death/thrash and jazz influences. Their technically focused songwriting crafts dynamic compositions with heavy grooves, odd time signatures, and sharp melodic passages.

The band was formed in 2023 by guitarist Jason Taylor who wrote first album of material and performed with Ratzilla until 2025. The current lineup consists of original members Greg Macdonald (bass) Angela Gram (guitar) and Ivan Pulido (drums).
