We like to imagine that a composer battle would be something like a duel between a rapper and a thaumaturge (lots of posturing, threats and obscure-yet-specific insults). And while that isn't what the Jacksonville Symphony has in mind, we can dream. Courtney Lewis conducts Brahms' "Symphony No. 3" and Bruckner's "Symphony No. 7."
8 p.m. Friday, April 6 & Saturday, April 7 at the T-U Center, Downtown, $19-$74, jaxsymphony.org.
