Ludwig Rosenberg, professionally known as Whitearmor, is a Swedish record producer from Stockholm.

He is a member of the musical collective Drain Gang, formerly known as Shield Gang and Gravity Boys, alongside recording artists Bladee, ECCO2K, Thaiboy Digital and Yung Sherman. He is also a member of VilloVilduVeta.

He started making songs in 2011 under the name DJ Cannabiz on a now deleted SoundCloud where he uploaded over 20 songs, both solo tracks and collabs, which of almost all are now deleted and lost – however, fan compilations do still float around the internet.

Whitearmor is most known for working with Yung Lean and Bladee. He has production credits on every Yung Lean album, executive producing Lean’s 2018 mixtape Poison Ivy and fourth studio album Starz.

In 2022, Whitearmor released an album called In the Abyss: Music for Weddings consisting of 10 tracks which are supposed to "potray different phases of love through the vague concept of wedding music". The album was described as being "a deeply romantic body of work that marks a bold and engrossing new direction for Whitearmor".
