The program features Shostakovich's Symphony No. 5, Beethoven's Coriolan Overture, and Tchaikovsky's Romeo and Juliet.
The concert was originally intended as a fundraiser for the SLSO musicians who initiated a work stoppage January 3, after rejecting a new contract that called for pay cuts.
Now that the musicians have approved a new contract, the concert is free.
Dana Myers, an SLSO violinist, said, "The St. Louis community was there for us during these past eight weeks, and this concert is to show our gratitude and say thank you St. Louis."
