About MesRowClb
MesRowClb is an independent electronic music label from Berlin.
Founded in 2025 by M. Hartmann and R. Rotter — two Berliners, two worlds. M. Hartmann brings four decades as a producer, DJ, and electronic musician, internationally toured and rooted in Berlin's club culture. R. Rotter comes from international real estate finance — Senior Vice President at Brookfield Properties, previously at Cushman & Wakefield and PwC. CPA, MBA.
Art meets structure. Sound meets balance sheet. The label is not a hobby project, but a company with artistic ambition and financial substance — built to exist for the long run.
We release slowly, carefully, and with intent. Every release gets its own space, every track its own time. No algorithm-rush, no interchangeable drops — just music that means something and stays. Deep house, tribal house, and melodic minimal techno — built for dance floors and for headphones alike.
Berlin as home. Rhythm as language. MesRowClb as the chapter that begins now.
MaHartmann
Berlin-based. Co-founder of MesRowClb.
Internationally, he has been touring since the late 80s as DJ Mesia — a specialist for Hip Hop, Breakbeats, and Electro Funk, an established name in the B-Boy and breakdance scene. Releases on labels from Sony Music and Warner to Berlin's underground. Full discography at djmesia.com.
As MaHartmann, he now opens a second chapter: electronic music between deep house, tribal house, and melodic techno. Independent, focused on organic textures, hypnotic rhythms, and arcs that get to unfold. Tracks that work on the festival floor at 3 AM as much as on the couch at 11 PM.
Two projects. One stance: music that means something.
The first official chapter as MaHartmann: the album "AnFi" (2025), followed by "TriBerl" and "Tonight" — all on MesRowClb.
