Among the projects is upcoming effort Ten Billion Hearts, which will feature a symphony orchestra and remakes of some of his classic hits, like "Isn't She Lovely."

"It is a lot of things that I have done, old material, but doing it a different way," he told Rolling Stone, who interviewed him backstage. "I'm going to do about three or four new songs as well. We did 'Isn't She Lovely' with the orchestra and I wrote another verse to it. This is just another interpretation, and we did the arrangement a little differently and it turned out really, really good. I'm really excited about it."

He added that he'd be up to return to the Los Angeles venue as a headliner in 2014 to support his forthcoming albums, which also include a gospel album dedicated to his late mother.
