Cavaille-Coll's Monumental Organ Project for Saint Peter's Rome

<I>Cavaillé-Coll's Monumental Organ Project for Saint Peter's Rome: Bigger Than Them All</I> by Ronald Ebrecht tells the engrossing story of Aristide Cavaillé-Coll's quest to build the largest-ever mechanical-action organ in the biggest church at the time. Cavaillé-Coll is often referred to as the greatest organ builder of all time and his efforts to build this impressive organ were complicated by intricate intractable problems. Saint-Peter's Square now a part of the Vatican City State was then part of the newly-united Italy which had just deposed the pope as ruler of the center of Italy and taken over the papal lands. It was a part of the Italian state so hotly contested that the Italian Republicans would not accept an organ hanged from the basilica wall lest the nearby oft-disputed boundary shift. Before or since has the music sphere ever provoked such a question that could bring nations to swords?
