Director Daniel Anker's ambitious film, “Music from the Inside Out,” showcases performances of Philadelphia Orchestra members, who also discuss what music means to them. Included are comments from violist Judy Geist, cellist Udi Bar-David, trombonist Nitzan Haroz and violinist David Kim. “I feel like I'm the luckiest guy in the whole world,” says Kim, regarding his work with the orchestra. “I can play the greatest music ever written.”
