Tuxtax

Tuxtax is a Swedish music and audio production company based in Stockholm, operating through the legal entity Tuxtax AB. It is the creative vehicle of composer and multi-instrumentalist Carl-Johan "Oa" Sevedag, who scores films, television series and video games, writes songs and produces tracks. The company's official website presents Tuxtax as both a personal composer brand and a production banner, with a portfolio that includes feature films, documentaries, trailers and interactive media. Sevedag was born in 1987 in Skåne, Sweden, and raised in Spain before settling in Stockholm. His breakthrough came at age 23 when he composed the score for the multimedia documentary Clouds Over Cuba, which won an Emmy Award at the Annual News and Documentary Emmy Awards. That project launched his screen-composition career. Through Tuxtax, he has since worked on a wide range of productions, including the 2023 drama Opponent (Motståndaren), directed by Milad Alami, which became Sweden's official submission for the Academy Awards; the Netflix survival thriller Red Dot, directed by Alain Darborg; and Bartosz M. Kowalski's horror feature Hellhole. Other credits include Locals (Stammisar), Horizon Line, Top Dog, Doris & Bettan – Marbella Mayhem, and the children's mystery Villain of Villains (Skurkarnas Skurk) from SF Studios. Beyond film, Tuxtax has a presence in interactive media. Sevedag's game-scoring credits include the horror-tinged Decrepit and the space-combat epic Jump Ship. He has also produced trailer music for major franchises, including Destiny 2: Shadowkeep and Dungeons & Dragons: Honor Among Thieves, as well as the FIFA 19 "Champions Rise" launch trailer. In addition, he created an official remix of Beck's "E-Pro." The Tuxtax name itself is explained on the company's website as a Swedish onomatopoeia (masculine noun) expressing the sound of blows — "whack, crack." The company is registered in Stockholm with organization number 559070-8086 and VAT number SE559070808601. It is a private limited company (aktiebolag) and is not publicly listed. Tuxtax operates primarily as a composer's studio and production company, taking on commissions for film, television, games and advertising, rather than as a traditional record label with a roster of signed artists. Its output is closely tied to Sevedag's personal creative identity, and the website serves as both a portfolio and contact point for potential collaborators.

The company is registered in Stockholm, Sweden, at Wollmar Yxkullsgatan 10, 118 50, with organization number 559070-8086 and VAT number SE559070808601. The name "Tuxtax" is a Swedish onomatopoeia (masculine noun) expressing the sound of blows — "whack, crack" — a playful nod to the percussive and impactful nature of music and sound design. Sevedag was born in 1987 in Skåne, Sweden, and raised in Spain before settling in Stockholm. His breakthrough came at age 23 when he composed the score for Clouds Over Cuba, an ambitious multimedia documentary that won an Emmy Award at the Annual News and Documentary Emmy Awards. This project launched his career in screen composition and established the foundation for Tuxtax's later work. Through Tuxtax, Sevedag has built a diverse portfolio spanning film, television, games and trailers.

Kowalski's horror feature Hellhole; Måns Nyman's debut film Locals (Stammisar), for which Sevedag created a 1960s-inspired period score; Horizon Line; Top Dog; and Doris & Bettan – Marbella Mayhem. Current projects include the Polish psychological horror-thriller 13 Days Until Summer (13 dni do wakacji) and the forthcoming children's existential mystery Villain of Villains (Skurkarnas Skurk) from SF Studios and Alain Darborg. In interactive media, Sevedag's game-scoring credits include the brooding horror atmosphere of Decrepit and the futuristic space-combat epic Jump Ship. He has also produced trailer music for major franchises, including Destiny 2: Shadowkeep, Dungeons & Dragons: Honor Among Thieves, and the FIFA 19 "Champions Rise" launch trailer. Additionally, he created an official remix of Beck's "E-Pro." Tuxtax operates as a private limited company (aktiebolag) and is not publicly listed.
