Cyndi Lauper has said going back to singing the blues after her successful pop career was "inevitable".
"I started in a Janis Joplin cover band and the bad thing was nobody was listening," the Girls Just Want To Have Fun star said in an interview.
"To go back to square one at this time in my life is really important for me. Everything is all based on the blues and to go back was a great gift. To go back with a high rhythm section was an even better, greater gift."
Lauper fans heard songs from her latest project, Memphis Blues, as well as such pop classics as Time After Time and True Colours during a closing, debut performance at the New Orleans Jazz And Heritage Festival.
"I've always wanted to play at the jazz festival," she said. "I'm so excited."
She reiterated that on stage to the thousands of people jamming the field to see her. Her set opened with a nod to New Orleans' second-line tradition, as she danced on stage waving a black and blue umbrella before moving into her rendition of Shattered Dreams, which drew rousing applause.
Cyndi, 57, said she loves the city of New Orleans and though she's never played the festival before she has performed at some of the city's other well-known music houses.
"All I know is, is that I love New Orleans," she said. "It's one of the jewel cities of America and music-wise, it's a place that is revered by many musicians. Just to be able to play at the festival is such a big, big deal."
Memphis Blues, released last June, debuted on the Billboard Blues Album Chart at No. 1 and remained there for 14 consecutive weeks.
