It’s been several years since I visited the Perez Art Miami Museum (PAMM) and on my recent trip to this amazing city, I stopped by to reconnect.   This is truly a unique institution with a mission of serving international contemporary modern artists of the 20th and 21st centuries committed to advancing a more inclusive, humane society.  The museum is constructed on a  20-acre museum park on the Biscayne Bay surrounded by spectacular views of skyscrapers on one side and the ocean on the opposite side.  Once inside this uniquely designed building, there were several new exhibitions, of which two caught my attention. Both are by deceased Latinos artists who are not as wel known yet have made significant contributions to the art world. The following is a little about Marisol Escobar and Carlos Cruz-Diez——both pioneers in the Pop Art and Optical Art movements.
