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.

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.

Initially inspired by the unique and soulful neoclassic-electro scene around Berlin and Iceland, he lives “between” these two regions in Northern Germany and tries to redefine and develop these ideas and approaches from a very personal point of view. For years he played with several bands as a live musician (including a period of time with Nils Frahm in his early days), 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 to perform live and also working on a new production releasing 2024.
