Pieces of music, as WNYC's Sara Fishko tells us, can change in impact over time. On the 80th anniversary of a beloved violin concerto's premiere, Sara and guests consider the case of the American classical composer, Samuel Barber, in this episode of Fishko Files.

Hilary Hahn's Barber & Meyer: Violin Concertos and Isaac Stern's Barber: Violin Concerto, Op. 14 are available on Amazon.

Hilary Hahn's upcoming album Paris is set for release next Friday, March 5, and is available for pre-order.
