Los Angeles artist Judith Francisca Baca is the doyenne of Hispanic American muralists and, not surprisingly, one of the most willing to forge ahead with the medium. Her new mural at DIA -- a monumental paean to immigration based on the flight of her own grandparents from Mexico during the revolution -- briefly nods to the old fresco mural style in content before jettisoning off into the 21st century. And when you consider where it's displayed, in the main terminal of the controversial little airport that could, the fifty-foot mural, featuring digital imagery applied to a foil background, seems even more perfect for the times. Welcome, Baca.
