Who is the composer of the piece performed by Hilary Hahn with the Oslo Philharmonic?

The piece performed by Hilary Hahn with the Oslo Philharmonic is a work by Felix Mendelssohn, which is well-known for its lyrical melodies and rich orchestration. Mendelssohn's compositions often showcase technical brilliance and emotional depth, making them popular in concert settings.
