Marcel Krömker is a double bassist, composer, and bandleader based in Berlin, with over 20 years of international touring experience across 24 countries on five continents. Known for his deep groove and creative versatility, he studied at the Conservatorium van Amsterdam and the Jazz Institute Berlin — taking masterclasses with Bobby McFerrin, John Scofield, Richard Bona, and bassists Mike Richmond and John Clayton — and has since built a reputation as a compelling voice in jazz and contemporary music.
Since 2007 he has recorded for Traumton, ACT, and Laika, and shared stages with artists including Nils Landgrén, Toni Lakatos, and Changuito. His project Marcel & the Bathing Birds — whose album Tweet! features New York trumpeter Alex Sipiagin — brings together original composition, free improvisation, and a sound that moves fluidly between the acoustic and the electronic.
Alongside his work as a performer, Marcel is founder and composer of Terz im Viertel, a children’s jazz ensemble that creates immersive concert experiences combining storytelling, improvisation, and live performance. The project — recognised by Initiative Musik for its artistic and educational impact — introduces young audiences to jazz through movement, imagination, and active participation. Marcel also draws in his spare time, and has begun designing album artwork for other artists.
