Saying Farewell Through Words and Music. The KSO returns to the venue of its very first concert in 1992 ? Greaves Concert Hall (NKU) ? for Gustav Mahler?s final complete composition ? his Symphony No. 9. A poignant musical farewell, this parting opus will be juxtaposed with original poems written by U.S. Poet Laureates as a reflective summation of their own lives and works. The KSO will adopt the safety protocols of each respective venue that are in place on the date of the performance. Capacity is limited.
