Hannah Ishizaki, a junior at Mount Lebanon High School, a violinist and composer, a member of the Pittsburgh Youth Symphony Orchestra, and leader of the Montgomery Quartet has already heard several of her compositions performed by Ovre Arts in Pittsburgh. She becomes the youngest woman composer ever performed by the Pittsburgh Symphony with the world premiere of her “City of Bridges” at the Pittsburgh Symphony Fiddlesticks concert conducted by Francesco Lecce Chong on February 18th.  She sat down for a few minutes in the Grand Lobby of Heinz Hall just after a performance for the PSO Friends.
