Scott Yoo investigates the story behind Vivaldi’s Four Seasons – and discovers a new Vivaldi work, his connection to Stradivarius, a treasure trove of original manuscripts, and that Vivaldi himself was almost lost to history.

In Germany, Scott discovers a riddle that Bach left in his only official portrait. In trying to solve it, he and his wife Alice Dade, also a star musician, discover Bach’s true personality and his surprising influences, leading them to a spectuacular finale in Paris.

Scott goes on the trail of Domenico Scarlatti, the most influential composer you’ve never heard of. From Italian, Spanish, Moorish, Jewish, Gypsy, dance and guitaristic roots, Scarlatti created a new musical language, more relevant today than in his own time.
