It's an opera described as "an artillery of brass and a battery of percussion." The Jacksonville Symphony is performing Sir William Walton's Belshazzar's Feast tomorrow night. You can still get tickets if you want to see the performance. It's at 8 P-M at the Jacoby Concert Hall. For more information - go to Jax Symphony-dot-org. Joining me now is .... Gabe Preisser - the baritone soloist. He's performing Toreador from the Opera Carmen. 3 3 .
