Tostiej a.k.a. Joost Knipping (1994) is a Dutch artist based in The Hague. His art focusses on abstract paintings in the neo-expressionism traditions, and is inspired by his art heroes Basquiat, Banksy, Pablo Picasso and A.R. Penck.

Works by Tostiej are characterized as a balance between chaos and power. Each piece is unique in its own way by form, color and composition. Throughout his process of making art, he is constantly challenged by his emotions to find the right balance on his canvas to express himself.
