* The St. Louis Symphony Orchestra has postponed its 20-day February tour in 16 European cities because the Persian Gulf War has resulted in "an impossible situation" of "interminable travel delays due to increased security measures" and "dramatically reduced concert attendance as a result of potential anti-war activity."
Instead of touring Great Britain, Germany, the Netherlands, France and Austria, the orchestra, led by Leonard Slatkin, will tour the state of Missouri for a month-long series of special concerts leaning heavily on American composers. The Baltimore Symphony Orchestra recently postponed its 1992 tour of Europe for economic reasons.
* The Opera Company of Philadelphia has named Robert B. Driver, artistic director of Opera Memphis and the Indianapolis Opera, as new general director, replacing acting general director Jane Grey Nemeth. Driver was picked over 40 candidates and will assume his job now. Danielle Orlando is the company's artistic administrator.
