In anticipation of the upcoming big band concert featuring a new arrangement of “Porgy and Bess,” Jazz Artists of Charleston is presenting its third JAC(K) Talk on Thursday at Redux Contemporary Art Center, 136 St. Philip St.

The event is free and open to the public. It begins with a 5:30 p.m. reception; the discussion starts at 7 p.m.

On the panel are Charlton Singleton, artistic direcor of Jazz Artists of Charleston and leader of the Charleston Jazz Orchestra; Leah Suarez, JAC’s executive director and CJO vocalist; Robert Lewis, saxophonist and arranger of the “Porgy” suite; and Walter Rhett, a Charleston historian. Adam Parker, arts writer for The Post and Courier, will moderate.

The talk will offer a glimpse of the process undertaken by Lewis and the CJO to reimagine this famous American folk opera set in Charleston, and the significance of the masterwork for the local community. The panel will take questions from the audience.

Redux will display a selection of photos and other objects from JAC’s digital archive.
