Campbell said he hoped to excite old fans and cultivate new ones who may not be familiar with hits that include "Tell Me What You Want Me To Do" and "I'm Ready."
"Everyone has that one song that's `their' song and they want to hear it, so we plan to accommodate them, but I might throw in some new stuff too," he said.

It was standing-room only, with fans from the back of the room to the tip of the stage. Long lines of people waited to get for the show, but most were unable. After his set, Campbell said the experience was great.
"I did all the classics, none of the new material as we had planned. They wanted to hear what they wanted to hear," he said. He did two encores, "Round and Round" and "Break it Down."
At an appearance last month in New York, Campbell gave the audience a taste of one his new songs, "Addicted to Your Love" and received what he described as positive feedback. "I mostly get asked, `Where have you been?' and they'll also say I look great and sound great - even though I'm all grown up," he said
Campbell said he's currently recording and working with a bunch of different people, including production from Teddy Riley and singer Faith Evans. He said his dream collaborations would be with rapper Drake, Neo and T-Pain and duets with Beyonce or Rihanna.

"There's always a place for great music," he said. "I think the music is a mix of everything I like from rock to rap but at my core, I'm R&B so it's R&B," he said.
He hopes to have two singles drop by the fall, with a full release sometime next year. "I'm independent right now and just trying to create some kind of buzz for myself. Ultimately, though, I'd be open for a 1 to 2 album deal," he said.
That's why, he said, he's not taking his appearance at Essence for granted. "It's kind of a big deal. There will be a lot of people looking and listening."
After significant success in the 1990s and early 2000s, Campbell dropped out of the music scene in his 20s. He tells The Associated Press that he spent that time "being humbled by life's experiences."
"Everything was kind of a blur," he recalled. "I was 11 when I started. By my 20s, there was a lot I didn't know and a lot I needed to learn. It took me a long time to do that."
In 1999, Campbell was ordered to attend Narcotics Anonymous meetings and an AIDS awareness class and fined after pleading no contest to a misdemeanor conviction for soliciting a lewd act from an undercover policeman. Campbell had been arrested in a police sting outside an elementary school in Van Nuys, California.
Campbell said after two successful albums - "T.E.V.I.N" and "I'm Ready" - he took time off to reflect on how his life was unfolding. "I went away to do Broadway," he said. "That was a humbling experience, working as part of a group. I went to Australia. I just started living and all those experiences I've now included on my new project that centers on being humbled."
"I think a lot of good things can happen as a result of this festival," he said. "I've truly been blessed and when it comes to God and his blessings all I can do is be prepared."
