Whitearmor

Ludwig Tomas Walther Rosenberg, known professionally as Whitearmor, is a Swedish music producer, multi-instrumentalist, audio engineer, and songwriter. He is best known as a member of the Swedish music group and artist collective Drain Gang. His production style has been described as softly textured and fluid, and his work is closely associated with the sound and aesthetic of the collective’s releases.

Whitearmor is part of Drain Gang alongside artists including Bladee, Ecco2K, Thaiboy Digital, and Yung Sherman. Within that circle, he is recognized primarily for production and studio roles, contributing as a musician and engineer in addition to songwriting. His credits extend beyond group material into collaborations and related projects connected to the broader Swedish internet-rap and cloud rap milieu.

In addition to his work under the Whitearmor name, Rosenberg has been credited under alternate aliases, including White Armor and Whitearmor93, and has also used the name DJ CANNABIZ. These names reflect different phases of his output and the way his work has circulated across online platforms and collaborative scenes.

Whitearmor’s genre associations are commonly linked to cloud rap, both through his own production approach and through his central role in Drain Gang’s catalog. His reputation rests on detailed, atmospheric instrumentals and a studio practice that spans composition, recording, and mixing, supporting vocalists and projects within his immediate network as well as outside collaborators.
