Creative Rationale

Over the equatorial Atlantic northwest of Cape Verde, where warm trade winds carry moisture across open ocean waters, the atmosphere holds a gentle energy - moderate winds from the northeast create rhythmic movement while relatively high humidity suggests the presence of tropical moisture. The substantial pressure gradient and wind activity inspire flowing, organic forms that sweep across the canvas like wind-driven currents, while the high humidity translates into overlapping washes of aqueous blues and greens that pool and bleed into one another with Frankenthaler's characteristic stain technique.
