Well, I wasn't too surprised, knowing that Philippe Jaroussky is the adored talented and spoiled child of the baroque music in Versailles. He's the most famous French countertenor, he sings like an angel, is native of Yvelines (was born in Maisons-Laffitte) and owes his last name to his grandfather and an impetuous French civil servant:
