Jan-Christian Groth alias Koltbach is a musician and producer whose music thrives on minimalist musical gestures and unconventional arrangements. It often has a meditative, cinematic atmosphere and narrative character. He worked with artists like Aparde, Johannes Motschmann, Nils Frahm (in his early days) and others.
His first release was „Debut“ in 2016 (ep). Since 2018 he appears non-exclusively on sub and main label of Springstoff (Berlin) with several releases since then.
He focuses on programmed tracks and sculpted sounds combined with live recorded acoustic instruments. Koltbach originally started out with classical guitar and plays various other instruments.
This project was initially inspired by the unique and soulful neoclassic-electro scene around Berlin and Iceland. Koltbach lives “between” these two regions in Northern Germany and tries to redefine and develop those influences from a very personal point of view. For years he played with several bands as a live musician, was a student of the brazilian musician and composer Dudu Tucci, studied music at the Humboldt University of Kiel, teaches music at a secondary school close to Hamburg and composes as an independent artist.
Koltbach is currently preparing for live performances and also constantly working on new productions.
