Antonio Vivaldi's Four Seasons is the most popular classical music work of all time. There are already over 1000 different albums with sales reaching tens of millions. It has become so common - in elevators, phone rings, or call center answering machines - that it has been condemned as the Muzak of the middle class. Rick Wakeman, a platinum selling avant-garde rock keyboardist and TV show Grumpy Old Man, believes that critics are wrong. He believed that "Four Seasons" was far ahead of the time, and it was actually the first concept album in history - Vivaldi was the world's first rock superstar. But how could a frail and sickly pastor from the 18th century create a prototype for Rick's modern style? Why did Vivaldi and Four Seasons remain unknown for over 200 years after his death? Rick became a detective to unravel the mystery: his journey took him to Venice - the most promiscuous city in the world in the 18th century - where he met some people who devoted their lives to studying and admiring Vivaldi... and exposed the sexual ugliness of a very modern rock star, which may have been the cause of Vivaldi's downfall. Rick had a conversation with Scottish performer Nicolas Benedetti and British composer Max Richter. In Venice, he found a super fan of Vivaldi who moved in from France every day to pay tribute to him; He met Vivaldi scholar Susan Orlando and writer Dr. Virgilio Boccadi, who wrote The Red Pastor. He also learned about the composer's relationship with Pieta, a school for abandoned children, from Mickey White, a former Wimbledon photographer who later became a Venetian. But the investigation also allowed Rick to find unexpected places and people. He met with avant-garde rock singer Mike Rutherford from Genesis and debated whose band Vivaldi would join; He met Croatian arrangers and keyboardists, and his Multinational Musicians Conference is turning the four seasons into heavy metal. Along the way, Rick also discovered the only existing original soundtrack for "Four Seasons" - a place that almost no one could imagine finding.
