In "Why Vivaldi?" Teddy Grouya leads us through unusual territory. Over the past several years there has been a surge of interest in the work of the great Italian Baroque composer Antonio Vivaldi. It is said that Vivaldi's music outsells all othe classical composers.Grouya visits with five Vivaldi devotees from different countries, different backgrounds, with different tastes- all of whom are fascinated by the music of Vivaldi.Grouya takes us to Venice where Vivaldi, known as Il Prete Rosso (The Red Priest), lived and wrote his music. We visit the very rooms which Vivaldi inhabited, the church in which his music was performed. Venice is probably the most filmed city in the world but Grouya leads us to see the place anew; his shots selected with a cinematic eye and wondrous affection for his subject. We meet a Baroque ensemble and time stands still as they play Vivaldi's music with the actual instruments of the time. In this lovely, compelling film you will find the answer to its title.
