Janine Jansen: A Rising Violinist Tackles Grieg Janine Jansen is a 28-year-old rising star of the violin. Last week, she was featured by the BBC at one of its lunchtime concerts from London's Wigmore Hall. We'll sample that concert and hear Jansen's performance of the Violin Sonata No. 2 by Edvard Grieg. Itamar Golan is at the piano.
