Commerce Germany January/February 2000 Stuttgart Chamber Member and Greek concert pianist Pavlos Hatzopoulos provided an unusual Business After Hours on December 7 with a lively lecture and concert devoted to Mussorgsky's piano suite "Pictures at an Exhibition". Reflecting the popularity of such lecture-concerts at company events, the Hatzopoulos event at the new Stuttgart College of Music was sold out. The German-born performer has given concerts around Europe and in the U.S., including one in honor of Vice President Al Gore in 1994.
