A Viennese black metal band founded in 1993, Trifixion were part of the founding nucleus of the Austrian Black Metal Syndicate alongside Abigor, Golden Dawn, Pazuzu, and Summoning — whose original 1993 lineup included Trifixion's Alexander Trondl on drums and vocals.

Trijumf are a Bosnian black metal band whose 2024 debut album Trijumf ili Smrt – Trijumf, released on Death Prayer Records, directly confronts the history of the Bosnian War.

Avant-garde black/death metal band from Plovdiv, Bulgaria—a city whose ancient Roman name, Trimontium, the band has adopted. Their 2021 demo, a four-track release, introduced their unconventional approach to extreme metal that blends black and death metal structures with more experimental and dissonant elements. Operating out of Bulgaria's second-largest city and former European Capital of Culture, they occupy a distinctive niche in the country's underground.

Trinacria emerged in 2005 from a collaboration between Ivar Bjørnson of Enslaved and noise artists Maja S.K. Ratkje and Hild Sofie Tafjord of Fe-mail, originally commissioned by Rikskonsertene as a concert piece.

Their debut full-length Travel Now Journey Infinitely documents this volatile synthesis.
