Watch Chris Brown Rehearse For Powerhouse Concert

We dropped in on his rehearsals in Virginia for Tuesday's New Jersey show.

On Tuesday (October 27), the same day [artist id="1961441"]Chris Brown[/artist] dropped a seriously cinematic video for “I Can Transform Ya,” featuring shape-shifting “Transformers”-like machines and martial arts moves, the singer is set to headline Power 105.1′s Powerhouse concert in East Rutherford, New Jersey.

Will his performance at all mimic elements of the video? What will Brown do for his first major event since his assault on former girlfriend Rihanna, and his first to promote his December 15 album, Graffiti ?
MTV News got a sneak peek at his rehearsals in a Virginia dance studio, which went a long way toward answering some of those questions.

Throughout rehearsals, a yellow Bumblebee mask from the “Transformers” movies sat on a desk nearby. As “Transform Ya” began to play, Brown and his dancers stood in a straight line, their heads bowed. A line from 2007′s “Tranformers,” delivered by Optimus Prime, played over the speakers: “They’re a young species. They have much to learn.”

Optimus then called, “Autobots, roll out!” and the dancers broke out into formation as Brown’s song came on. Throughout rehearsals, Brown’s dance lineup shifted. At times, he was joined by as many as six backup dancers, while at others only two toe-tapped next to him. For a few tracks, he alone danced to the beat.

Dressed in a black baseball hat, gray sweatshirt and T-shirt, rolled-up pants and high-top Nikes, Brown wasn’t all business during his practice time. He joked around a bit, pulled off many nifty tricks with his hat and at one point sat down to check his Twitter account on a Mac laptop.

Brown ran through “Wall to Wall,” “Kiss Kiss” “Yo (Excuse Me Miss),” “Take You Down,” “Gimmie That” and “Back to the Crib” in front of our camera, but we didn’t see him rehearse “Crawl,” the new track he dropped last week.
