ONLY SLIME

ONLY SLIME is elastic and radically adaptive.

ONLY SLIME is a shapeshifting artist duo founded in Oslo by Claudia Cox and Tobi Pfeil—fusing theatre, opera, digital art, and immersive technology into high-impact, genre-fluid performance and installation works. Since their explosive debut at Black Box Teater in Oslo in 2024, they have been touring AFTERLIFE across Europe, with their latest performance at Hebbel am Ufer, HAU3 in Berlin in October 2025. AFTERLIFE received international acclaim and was awarded Work of the Year 2024 by the Norwegian Composers Association, and was part of newspapers Klassekampen and Norwegian Shakespeare Magazine’s selection of top 25 stage productions in Norway since 2000.

With a bold, signature aesthetic that merges live motion capture, autotuned opera, electronica, black metal, and game engine worlds, ONLY SLIME create hybrid performance art landscapes where avatars glitch, forests burn, and queer mythologies take root. For them, slime is both symbol and strategy: elastic, emotional, radically adaptive.

Their work dissolves the boundaries between ritual and rave, body and screen—inventing a new theatrical and multimedial aesthetic language for a world in flux. ONLY SLIME was in residence at Det Norske Teatret, Oslo Norway in 2025, where they premiered their fantasy opera and festival DRAGONBLOOD, in collaboration with ULYSSES member Ultima Oslo Contemporary Music Festival and The International Fossefestival. The production was a sold-out success, earning a ★★★★★ review in Norway’s national newspaper Aftenposten, which hailed it as “the nerds’ revenge on theatre” and celebrated its bold fusion of technopop, metal, opera, gaming aesthetics, and immersive scenography.
