On the last day of University of Dayton Professor Sam Dorf's Ethics and American Popular Music class, he takes his students on a mini field trip to perform a piece about survival, about hope and about our collective rage. His class meets at the corner of Brown and L streets to perform a work by Yoko Ono from 1961. Voice Piece for Soprano instructs the students to do the following: "Scream: 1. Against the wind, 2. Against the wall, and 3. Against the sky."
