Chris Brown returned to the stage on Tuesday (Oct. 27) at Power 105.1’s Powerhouse ’09 concert for the first time since pleading guilty to assaulting Rihanna. Despite technical difficulties, the pop star braved the rain and thrilled the audience with his new single “I Can Transform Ya” with Swizz Beatz, wearing a Michael Jackson “Thriller”-inspired outfit.

Keri Hilson, Mario, Ryan Leslie, Fabolous, Trey Songz, Jim Jones, Omarion, and The-Dream also performed at the New York radio station’s annual show at the Izod Center in East Rutherford, N.J.
