St. Louis Symphony IN UNISON Chorus

The St. Louis Symphony IN UNISON Chorus is an auditioned ensemble of volunteer singers that performs a variety of musical styles, with a focus on the interpretation, performance, and preservation of music from the African diaspora.

Founded in 1994 by Dr. Robert Ray as an extension of the SLSO’s IN UNISON community engagement initiative, the IN UNISON Chorus performs several times each year with the St. Louis Symphony Orchestra and throughout the community. Chorus members often come from IN UNISON Program partner churches. Many chorus members sing in other vocal ensembles or church choirs. All share a love of music.
