Jakub Słomkowski is a painter, illustrator, musician, and installation artist. He graduated from the Academy of Fine Arts in Warsaw with a degree in painting under the supervision of Krzysztof Wachowiak in 2007. From 2004 to 2005, he studied at the Faculty of Fine Arts at the Complutense University of Madrid.

Since 2010, he has been composing music for performances by Iza Szostak (over 9 premieres in total), including Remix Merce Cunningham (Komuna Warszawa), The Excavator Ballet (Balet Koparyczny, Cricoteca), National Affairs (Nowy Teatr), Skaj is the Limit (CCA Ujazdowski Castle), and Trapeza (Studio Hrdinů). He is the founder of the musical band Andy Why and the duos Kubatwiceimprovise and Estamos Unidos. Since 2019, he has been developing his solo music project, I AM SORRY DAVE, whose informal origins date back to 1997. In 2022, together with Rafał Smoliński, he composed the score for Andrzej Jobczyk’s animated film Airborne, which won Best Short Award at the Oscar-qualifying Short Shorts Film Festival & Asia 2022. Alongside French musicologist Loïc Bertrand, he creates the performance series Icarus and Styx, presented at events such as Survival (Wrocław), Contexts (Sokołowsko), Learning from Warsaw (Porthos, CCA), and Festival des Idées (Paris).

His first project combining visual arts and music was Program Music Box—a work recognized in the Samsung Art Master 2009 competition and exhibited as one of the winning pieces at the Centre for Contemporary Art Ujazdowski Castle in Warsaw.

He is a member of the NZTB Association, served on the Programming Board of the ArtWalk Gallery from 2018 to 2025, and belongs to the informal artistic collectives Time New Roman and FreeBloopGroup. He is also the organizer of the recurring event Dinner at the Steelworks (Kolacja na Hucie), running since 2007.
