Houston artist Jonathan Leach has just finished a temporary mural on the walls of 13 Celsius, a Houston bar. Titled “Unwrapped,” the pattern of bright colors and zig-zag lines was inspired by traffic signs and will remain on view until February 15. Last year 13 Celsius comissioned a temporary installation by Houston artist Ariane Roesch, daughter of Houston gallery owner Sonja Roesch, who hosted a solo show by Leach last summer.
