Gilbert Durán, a self-taught artist whose work adorns many of the Alamo City’s most popular restaurants and businesses, died on Tuesday, according to social media posts by friends. Durán was a Southtown fixture, where he worked out of his Studio 911, producing colorful, dramatic paintings that could later be be seen on the walls of eateries including Rosario’s, SoLuna, Bohanan’s and Boudro’s.
