Classical Pranksters Don't Just Play Music: They Play With It

Collective Cadenza, or CDZA for short, is a loose-knit group of musicians — many of them graduates of Juilliard. They've made a name for themselves with funny YouTube videos that have received millions of views. As a result, the group was invited to perform live at the inaugural YouTube Music Awards alongside Eminem, Lady Gaga and Arcade Fire.
