Hilary Hahn speaks with composer Gillian Whitehead about her creative process and life in music. Hilary premiered Whitehead's piece "Torua" in October 2011 as part of the project, "In 27 Pieces: The Hilary Hahn Encores," a collection of new short pieces by 27 contemporary composers, for acoustic violin and piano. One interview with a participating composer will be posted every month.
