Riono Tanggul, also known as Tatang, graduated from the Indonesian Institute of the Arts Yogyakarta. Tatang's body of work exemplifies his interest in constructing and distorting forms. He experiments with various painting and drawing mediums to explore the depiction of forms, transforming them from tangible to intangible. Fragments, figurines, human anatomies, clothes, flora, and landscapes are commonly found in his works, appropriated and stripped of their function or meaning.

His works are mostly comprised of composition and juxtaposition of forms - structures that are assembled into figures that look familiar and recognizable, but they collide with each other, overlap and merge, encouraging us to challenge our perceptions and question the reality within them. Where an image or form typically possesses the characteristic of being absolute, Tatang manifests the role and the function of forms and images to be in between, creating a sense of ambivalence.
