Break out the fancy hats and let the good times roll.  Popular New Orleans concert series Jazz in the Park is coming to Austin for an ebullient afternoon of food and music in Republic Square Park on Sunday. The event is free and open to the public.

The festivities kick off at 1 p.m. with a second line parade that will begin at City Hall plaza and make a jovial procession to the park. Born from the same lineage as the city's jazz funerals, second lines regularly liven the streets of New Orleans' famous French Quarter on Sunday afternoons. According to the event organizer, "They range in size, level of organization and traditions, but in all cases they will include a brass band, jubilant dancing in the street and members decked out in a wardrobe of brightly colored suits, sashes, hats and bonnets, parasols and banners."

The parades meld "the pomp of a courtly function and the spontaneous energy of a block party," organizers say. The Austin second line will feature Sudan Social Aide and Pleasure Club and the All For One Brass Band, who have been involved with the NOLA concert series for seven years, alongside hometown faves, Minor Mishap Marching Band.

The party at the park runs til 8 p.m. and will feature music from NOLA's Corey Henry and the Treme Funktet, local blues standout Jackie Venson and Sweet Home Baptist Choir. A variety of restaurants from Austin and New Orleans will be on site serving Cajun favorites and soul food.
