The scorching duo in Pedro Alvarez’s “Tango Argentino” is so hot they are creating flames with the heat of their dance moves. Born in Argentina and originally employed in electrical circuitry, Alvarez was consumed with a passion for dancing that translated itself to painting. Most of Alvarez’s works are devoted to dance themes, and emphasize dances from South America, such as the tango. A prolific artist, Alvarez maintained a feverish work pace, which he expresses in sweeping energetic brushstrokes, which have become less aggressive since he recently moved to rural Spain.
