TCF is the moniker of Norwegian contemporary artist and musician Lars Holdhus.

His work explores themes of code, cryptography and musical composition through the use of visual, sonic, built and written concepts. Holdhus creates a world that draws references from musique concrete, hardstyle, hardcore, poetry and digital artifacts. His practice shifts between art exhibitions and performing music pieces.

The titles and descriptions of his work are written in cypher text. His releases on PAN and Liberation Technologies explored the cryptographic theme, consisting of digital and physical content containing the necessary keys to unlock the full meaning of the work.
