What artist is the greatest spontaneity and freedom?

One artist often celebrated for their spontaneity and freedom is Jackson Pollock. His drip painting technique embodies an instinctive, unrestrained approach to art, allowing the paint to flow and interact dynamically on the canvas. This method reflects a deep connection to the subconscious, representing a liberation from traditional artistic constraints. Pollock's work invites viewers to experience the energy and spontaneity of the creative process itself.
