Biography

Mustis made his first recorded appearances with Dimmu Borgir in 1998 and became a full member shortly thereafter. He played a significant role in the development of the band’s symphonic and orchestral sound and is credited as a composer on several key works from this period, including "Progenies of the Great Apocalypse" and "Eradication Instincts Defined" from the album Death Cult Armageddon (2003).

His studio work with Dimmu Borgir includes the albums Spiritual Black Dimensions (1999), Puritanical Euphoric Misanthropia (2001), Death Cult Armageddon (2003), the re-recorded version of Stormblåst (2005), and In Sorte Diaboli (2007).

Mustis departed Dimmu Borgir in 2009. Following his departure, he stated that issues relating to authorship registration and contractual matters would be resolved through legal channels.

In 2024, Mustis reunited on stage with Dimmu Borgir to perform "The Insight and the Catharsis" at the Inferno Metal Festival, alongside former members ICS Vortex and Tjodalv.

The surname Mustaparta is of Finnish origin and translates literally as “black beard”.
