CCJO Jazz@First | Mardi Gras Party featuring Queen City Vintage Vibe CCJO is breaking out the beads and king cake because it’s time to party! Jazz@First is bringing the celebration to life through a program fit for Bourbon Street. Hear music that will have you swingin’ in your seat from New Orleans marches to the music of Jelly Roll Morton to some of your Mardi Gras favorites like “The Saints Go Marching In!” And trust us, you’ll want to be in that number at First Unitarian Church for the most enjoyable Fat Tuesday event of the year.
