Leopold Mozart was upset with his willful son, who had lost his job with the Salzburg Cathedral, burnt his bridges with the archbishop, moved to Vienna to work freelance, and now had married some young singer from the city. He disapproved of all of it.
And now, young Wolfgang was returning to stage a new work for the hometown crowd -- which included a solo to show off his new wife.
Well, it couldn't hurt to see what the prodigal son had come up with.
What it was was the Great Mass in C minor, and it's our featured work for this Thursday night.
