Nodding with its title to a theme that trickled through the Henry B. González Convention Center’s earliest artistic focal points, “Confluence: Art at the Convention Center” seeks to provide visitors “with an art historical overview of San Antonio’s contributions to the visual arts” while “reflecting the city’s growth and dynamic connections to Mexico and Texas history.” Spearheaded by the City of San Antonio Department of Arts & Culture, art advisory committees and art historian/curator Ruben Cordova, the project incorporates works from guards both old (Jesse Treviño, Mel Casas, Alberto Mijangos) and new (Kelly O’Connor, Richard Armendariz, Jenelle Esparza). Timed with the Convention Center and Hemisfair Park’s 50th anniversary, “Confluence” opens to the public on February 1 in tandem with a HemisFair ’68 mini-exhibit curated by Rigoberto Luna.
