The Oak Ridge Symphony Orchestra (ORSO) is the longest-running symphony orchestra in the state of Tennessee. It started out as a volunteer organization in 1944, but today the orchestra is predominantly professional.

The Oak Ridge Chorus consists of avocational singers; anyone who loves singing and can attend weekly rehearsals is invited to sing. The Chorus will be singing with ORSO during two of this season's concerts.

All Symphony and Chorus concerts will be conducted by Dan Allcott, former conductor of the Atlanta Ballet Orchestra and professor of conducting and director of orchestras at Tennessee Tech University in Cookeville, where he also conducts the Bryan Symphony Orchestra.

The ORSO and ORSO-Chorus concerts begin at 8 p.m. Saturday at the Oak Ridge High School Performing Arts Center (see map) except where noted.
