"Heavenly Harmony" by Peter Estarchazi plays with five centuries of European history. In the first part, amidst a storm of fragments of collective memory ("my father"), powerful personalities of the great Estarchazi family pass through, counts, generals, prime ministers, but also traitors, tyrants, pedophiles, drunkards or common people. The second part focuses on the biological father of the author and his journey towards the harsh leveling of the 20th century.
