My son was hailed by all of Vienna not only as a great pianist, but as one of the greatest and most controversial composers of his time. But I saw it first. I nurtured that talent in him. I had helped him become what he now was.

On a stormy evening in February 1785, the elite of Vienna gathered to hear a new work from Austria's leading virtuoso pianist - Wolfgang Amadeus Mozart. The importance of what lay within this masterpiece was known to only one man - Leopold Mozart, the composer's estranged father.
