Tractata is an Ostend-based non-profit organisation (vzw) founded in 2026 by saxophonist and composer John Dikeman. It is the home for his artistic work: it produces and presents his projects, organises concerts, and releases recordings through its own label. Tractata’s work centres on jazz, free improvisation and experimental music, with a focus on collaboration across scenes and disciplines. Rooted in Ostend and active internationally, Tractata connects the local scene with musicians and audiences across Europe and beyond.
