Bluestem is a native prairie grass and can be found across the North Texas region where Hill's home and studio are located. Work in the series is produced in several steps. Bluestem is carefully selected for its potential to create impressions in acrylic paint on canvas while exposed to the weather. After weathering, the work is then brought into his studio where forms and patterns are discovered, taped off and painted over. Through a process of adding and subtracting, an under-and-over-painting is created. The result is a unique visual language of contrasting patterns which express reductive forms and space.
