Oscar-winning composer Gustavo Santaolalla (BABEL, BROKEBACK MOUNTAIN) guides us on a journey into the golden age of tango music. The occasion is a once-in- a-lifetime reunion of the leading lights of tango from the 1940s and 1950s, now in their 70s and 80s, as they prepare for a concert at Buenos Aires’s landmark Teatro Colón. Wonderful performances alternate with warm recollections among the musicians, many of whom haven’t seen each other—let alone performed together—in years.
