Matthews is best known for abstract cityscapes marked by white geometric motifs. In his paintings produced in New York City, Matthews favors taupe backgrounds with abstract representations of bricks, water towers, and pigeons. His Los Angeles-based works feature sunset-inspired gradient backgrounds and are reminiscent of paintings by Ed Ruscha. These compositions include organic, foliage-like shapes to reflect the lush environment. Regardless of style or location, Matthews highlights bustling urban environments that appear intimate and serene. The artist recently began working with pastels in his “Vortex” series, which features swirling rainbows of color.
