Ravinia’s slate of six off-season concerts this fall and spring will cost only $10 each. Last year admission to these concerts was $25 each. The price was lowered in an effort to broaden the audience for these top talents in the classical world. Patrons can save an additional 20 percent when they put together their own series of four concerts. Concert/dining packages that include a three-course meal are only $40 each. Tickets are on sale now.
