Legend has it that Abner Doubleday, a Union soldier, shaped baseball’s first home plate after our own Fort Sumter, which he defended from the Confederates during the Civil War. Of course, that’s been pretty much disproved, but at least Charleston can still claim responsibility for the spread of jazz music. We’ve got the circa-1891 Jenkins Orphanage Jazz Band to thank for that. The RiverDogs and Jazz Artists of Charleston are coming together to celebrate these two American-as-apple-pie institutions with the first Jazz Night at the Joe. “We want to entertain the fans in unique ways, and baseball and jazz are a great cultural and local fit,” says Mike D’Antonio. Charlton Singleton will lead the JAC’s Swingin’ BANDits ensemble through the national anthem at 6:55 p.m., and they’ll also play through the seventh inning stretch and during the post-game fireworks. As for the baseball, the RiverDogs will face off against the Kannapolis Intimidators.
