CASTLE is an American heavy/doom metal band formed in 2009 in San Francisco, California. Known for their heavy, traditional doom sound mixed with 70s and 80s metal influences and occult themes, the group consists of core members Elizabeth Blackwell (vocals, bass) and Mat Davis (guitar, vocals), frequently performing as a power trio with various touring drummers.

The band made an impact early in their career when their second album, Blacklands (2012), was nominated for a Canadian Juno Award for Metal/Hard Music Album of the Year. Renowned for their relentless touring schedule, CASTLE has played over 700 shows globally across the US, Canada, Europe, and Japan.

Their latest album, Carrie Chains, was released on the 4 th of September 2026 via Hammerheart Records. It shows CASTLE at new heights of constructing their trademark serpentine riffs into powerful anthemic hooks while the whiskey throated vocals of powerhouse singer Liz Blackwell fill every spooky nook and cranny to intoxicating effect. Taking influence from the 70s/80s riff-heavy maestros like Black Sabbath, Judas Priest and Mercyful Fate and keeping a stripped-down attack sound, CASTLE channel that classic heavy-metal DNA into something leaner, meaner, and unmistakably their own.
