Painter Duy Huynh has come a long way since his first commission in the third grade: He sold a drawing of the Teenage Mutant Ninja Turtles for $2 and a week’s worth of chocolate milk. Huynh’s art has practically become the public face of East Nashville’s Art and Invention Gallery, and his latest show isn’t so much an exhibition opening as a celebration of the artist’s nearly yearly contributions to the space. Born in Vietnam, Huynh now lives in Charlotte, N.C., where he and his wife — the artist Sandy Snead — have recently opened the gallery/boutique Lark & Key. Huynh’s Nashville shows always draw crowds of locals to see the latest fantastic narratives the painter has dreamed up. New painting “Flourish” features brighter colors than the artist has typically used in the past, rendered with more clarity and confidence. He’s become a better painter, but titles like “The Horseradish Whisperer” suggest that while he takes his work seriously, he’s not above having a little fun.
