In 1988 approximately 50 young from the Soviet Union and 50 young musicians from the US came together at Oberlin College for a week of rehearsals that were followed by a tour of the US and a tour of the Soviet Union. Most of the musicians were college age, and among them was my son, Rick Graef (now Asst. Principal Horn in the Indianapolis Symphony Orchestra).
We lived in the greater Chicago area at the time, but Chicago was not on the American tour. The closest the orchestra got to Chicago was Brookfield, Wisconsin. I don't know where else they played in the US with the exception of Carnegie Hall in New York City. I will never forget the opening of the Brookfield Concert, which started with Copland's Fanfare for the Common Man. I teared up with pride and the awesomeness of the music.
