It was filled with lead dust, but it had not burned.

The organ was then subject to a comprehensive deep clean, decontaminating it of any other toxic lead soot.

It wasnt possible any other way, Latrytold CNN.

During the day it was impossible to do anything [with the noise].

Because the stone is so clean, there is no dust, Latry explains.

During Notre-Dames grand reopening, Latry awakened the organ in an incredible 10-minute musical ritual.

This wake up of the organ is something really incredible, he admits.

Eight times the archbishop will call to the instrument.

The first one, for example will be, Organ, holy instrument get up!
