The artists, (mother) Michèle Deiters and (daughter) Bibi van der Velden, first began collaborating at the bequest of a friend and contemporary art collector for his sculpture garden in France, and it was a near-immediate revelation for both their artistic practices. 
According to Simon Levie, former director of the Rijksmuseum, "Bibi and Michèle complete one another, automatically complementing and fusing their energies. Just as naturally they see into each other's brains while working and don't shy away from building on each other's thoughts. They work and create together in a way that gives new meaning to the words ‘working together’. What Michèle and Bibi do strikes me as completely unique."
