Creative Rationale

Over the Chicago lakeshore where Lake Michigan meets the urban edge, a powerful storm system churns with low pressure and strong winds cutting across the water from the northeast. The cold temperature anomaly and high precipitation create dense, turbulent atmospheric conditions that translate into heavily clustered brushwork in cool steely blues and greys, with wind-driven diagonal gestures sweeping across a darker ground that reflects the low barometric pressure. The 83% humidity and active precipitation manifest as overlapping paint-like forms that accumulate in energetic groupings, while brief passages of luminous yellows and greens pierce through like memories of warmer seasons.
