Hamilton's wife, Frenchell Pannell-Hamilton, said she enjoyed the rapper's performance.
"We have to support our local musicians and stand behind them," she said. "That helps keep New Orleans strong."
Tony Jones, visiting from Hawaii, said he didn't know what happened to get Mystikal a return ticket to prison, but hoped "the judge was lenient."
Jason Foster, a Charlotte, N.C. native now living in New Orleans, said he grew up with Mystikal. This was his first time at the Jazz Fest and his first time seeing the rapper's live show, which included music by his full brass band "Hot Sausage."
"He played all his hits and gave a great show," Foster said.
Tyler pleaded guilty in 2003 to forcing his hairstylist to perform what a judge called "continuous sex acts." The victim in that case accused Tyler and two bodyguards of making her perform oral sex after accusing her of stealing $80,000 worth of his checks.
The woman denied stealing any money.
