In the 80’s, Craig Costello (born in 1971, lives in Brooklyn) starts painting in the street under the name KR. He then studies photography at the San francisco Art Institute. Back in New York, he stands out by his use of a liquid ink that he makes himself: Krink (for KR Ink). Soon he removes the letters from his paintings to keep exclusively the drips, falling like a sudden rain that he spreads on many elements of the public space. He is exhibited in numerous galleries since the 2000’s (Owhow in Los Angeles, The Hole in New York, Galerie du Jour agnès b. in Paris) as well as in worldwide institutions like Los Angeles MoCa, Museu Da Imagem E Do Som in Sao Paulo or Pera Museum in Istanbul.
