The Second Line is a tradition in parades organized by Social, Aid and Pleasure Clubs (SAPCs) with a brass band parades in New Orleans, Louisiana, United States. The “main line” or “first line” is the main section of the parade, or the members of the SAPC with the parading permit as well as the brass band. The Second Line consists of people who follow the band to enjoy the music, dance, and engage in “community.” The Second Line’s style of traditional dance, in which participants dance and walk along with the SAPCs in an African-based, free-form style with parasols and handkerchiefs, is called “second-lining”.

“During the “second line season”, lasting most of the year with breaks for holidays (including Mardi Gras) and the hottest part of summer, there are second line parades most Sundays.[5] Longer parades often make stops, commonly at bars, where refreshments have been arranged for members and those following the parade for fun can purchase something. There are often vendors selling soft drinks, beer, and street food, including barbecue and yaka mein. “
