It's the 16th annual Tallahassee Jazz and Blues Festival.
Six different groups take the stage, performing a variety of music.
The fun-filled family day also features activities including arts and crafts.
"I like the mixture of the cultural event with the context of the zoo, so it's a very nice combination", said Talinn Grigor, who attended the event.
Some of the money raised benefits the Tallahassee museum's education programs.
And, if you didn't get a chance to see Saturday's show, five more groups are performing Sunday from 12-5.
