Violinist Tim Fain is a poster child for this new musical openness and ecumenicalism. But beyond just mixing genres, he is also fascinated with how music can engage more of the senses and interact with dance and film and new technologies like the fast-evolving realm of virtual reality. Chicago audiences will get a taste of Fain’s wide-ranging interests when he teams up with longtime friend, pianist, and Academy Award–nominated composer Nicholas Britell, for “Once Upon a Score,” a touring multimedia program that will make its debut on December 2 at Ravinia. Through music, visuals, and commentary, they will explore some of their collaborations in the realms of dance, virtual reality, and especially film. Britell is best known for his scores to Free States of Jones (2015), and this year’s Best Picture Oscar winner, Moonlight—excerpts from all three will be featured, as well as highlights of other projects that the two have worked on in one way or another.
