The Berlin Wall was constructed in 1961 as a physical barrier between East and West Germany. For 28 years the Berlin Wall was the symbol of the Cold War and State Repression. "Rio Diablo" is a tribute to Freedom Fighters and People who oppose Dictatorship and Injustice. Symbols are images in simple forms representing a collective belief or territorial integrity. Rulers - good as evil - have always made use of symbols in an attempt to preserve the status quo. Rio Diablo is filled with such symbols. Most significant is the river, causing death and destruction if you try to cross it. But superstitions, prejudices and conventional thinking are also part of the story. Fortunately it is so wisely that restrictive symbols can be replaced with prospective symbols. That too is part of the story.
