​​

Kallias is a progressive death metal band fronted by guitarist and vocalist Nicole Papastavrou, with Chris Marrone on bass and vocals, Erik Ryde on lead guitar (also of Galactic Empire), and Justin Gogan on drums. Their sound blends influences from Meshuggah, Opeth, Decapitated, and Extol, showcasing a balance of aggressive riffs and catchy melodic choruses, all played on 8-string guitars.

 

The band has made waves with notable collaborations on their debut album First Ascent, featuring guest solos from Jeff Loomis (Nevermore, Arch Enemy), Greg Burgess (Allegeaon), Rafael Trujillo (Obsidious, Daath), and Ole Borud (Extol) on the single "Mouthless Embassy." Their music is a fusion of technical precision and emotional intensity, with a panoramic sound that demands attention.

 

In 2024, Kallias is working on their highly anticipated second album, which is set to release in 2025.​
