Music from the Inside Out

Anker begins his documentary with the question, what is music?—a query that even his subjects, the 105 seasoned musicians of the Philadelphia Orchestra, struggle to answer. Their inability to fashion a satisfying response gives the film an unfocused, somewhat haphazard air. But maybe that's the point: Though all part of the same classical ensemble, each of the individual members has his or her own distinct personal attachments to nearly every variety of music, whether playing it, hearing it or recalling it. It's a concept that both band geeks and Britney fans (especially Britney fans) can appreciate.
