Ravinia will present an encore screening of this year’s Oscar winner for Best Documentary Short Subject, The Lady in Number 6, in Bennett Gordon Hall with free general admission to ticket holders for the Monday, Aug. 25, performance by Pedja Muzijevic featuring Chopin’s complete Op. 28 preludes. The film tells the riveting, true story of the world’s oldest pianist, who also happened to be the world’s oldest concentration camp survivor, Alice Herz-Sommer. Chopin was a particular favorite of the 101-year-old, who died just one week before the film won the Oscar. The 38 minute film begins at 4:45 p.m. with the concert starting at 6:00 p.m.
