It's a truly disturbing act of violence. A musician in New York City viciously bashed in the head by a random stranger. The woman lurks behind him, moves in, then picks up the cellist, metal water bottle, and waxes him. In the middle of one of the songs that I was doing, I just felt this impact, this terrible crashing pain along the back of my head. 29-year-old Ian Forrest is a 30-year medical student at Mount Sinai Hospital in Manhattan who also plays in the subway for the pure joy of performing for people. Please welcome Ian Forrest. He's such an accomplished cellist, he was invited to play the national anthem at Madison Square Garden last December. But what just happened to him is leading to outrage across the city. It does, you know, anger you that just in the subway station you're doing your own thing that that could all be broken in a quick moment with an active violence in hatred.
