When Georg Solti accompanied the remains of Bela Bartok back to their mutual Hungarian homeland last June, Solti was emotionally overwhelmed by the experience. A single rose left on the master’s coffin became a symbol of the debt of gratitude that his former pupil felt. The Solti/Bartok collaboration is legendary; add to that the Chicago Symphony, and you have music making of the finest order. If you’ve never had a chance to hear the city’s cultural jewel under the man who propelled it to international acclaim, this first concert of the 1988-89 season is the perfect opportunity to do so. Solti’s days in Chicago are numbered, and this will likely be the last time we’ll have a chance to hear him interpret Bartok’s supreme masterpiece, the Concerto for Orchestra. Also on the program are the Haydn Symphony no. 101 (“The Clock”), and the suite from the Tchaikovsky ballet Swan Lake. It’s an unusually balanced program, spanning the 18th to the 20th centuries. Tickets are likely to be scarce, but not impossible to obtain, especially on the concert day itself–there are always turn-backs from subscribers. A new policy makes tickets available to students and seniors at half price (not to exceed $10) after 5 PM the day of the performance. Tonight and Saturday, 8 PM, Orchestra Hall, 220 S. Michigan; 435-6666.
