Katharina Grosse is a Berlin-based visual artist. Her site specific work teems with a spectrum of vivid colors that are overlaid on walls and a range of materials (like rubble, concave structures and large spheres). Using an industrial spray gun, Grosse’s process is very physical (you can check out a video of her painting here). While there’s a conceptual basis behind her work, her process really resonates with our primal instinct to write on walls- which the Aurignacians first did 32,000 years ago and graffiti writers continue to do today. Grosse’s work also resonates with our inner child via our desire to paint on things we’re told by authority figures not to paint on.
