David Garrett brings his violin to a free concert in Milan's Piazza Duomo square, where he will perform with the Philharmonic Orchestra led by Riccardo Chailly. Garrett is accustomed to both outdoor concerts and large audiences. He owns a Stradivarius and a Guadagnini violin. While some criticize his rock and pop covers or modeling work, Garrett believes the quality of his music is most important. He identifies with the violinist Paganini but says acting in a movie about him was just for fun.
