Grammy Award-winning violinist Hilary Hahn discusses her most recent recording, "In 27 Pieces," which is the culmination of a multi-year project. Hahn commissioned 26 composers from around the world to write short-form works, suitable for use by violinists as performance encores. For the 27th encore, she held an open contest that drew more than 400 entries.
