In “Composition,” primitive, emotional responses come from the urgent whirlwind of color and motion by pioneering Abstract Expressionist Jackson Pollock (1912 – 1956). The groundbreaking artist, who relieved inner turmoil through painting, is known for his psychic automatic style of painting, a stream-of-consciousness technique of pouring, dripping and flinging paint, sand and glass onto large canvasses with dramatic physical movement with no identifiable focal point. Pollock’s visionary work made him the most important figure in the most important 20th century artistic movement.
