Mos Def - who is currently in Louisiana rallying in support of the "Jena Six" students - expressed anger over the seemingly lack of response in the hip-hop community.

"Shame on everybody who's not here," the Brooklyn rapper told MTV News, referring to the Sept. 20th demonstration in Jena, Louisiana.

"I'm f*cking mad. I'm disappointed to always be coming to these things and it's only one or two people [from the music industry here]. If you ain't gonna use your voice, then be quiet. I'm disappointed and ashamed."

Community leaders voiced outrage over the trial of six Black teenagers, who initially faced attempted-murder charges last year for the beating of a White student.

Bun B, of the rap duo UGK, also appeared at the rally after reportedly driving over from Port Arthur, Texas.

"I grew up right next to a town where it's strictly White people," Bun said.

"I've been privy to these small incidents of violence in these all-White towns. We were blessed to find out about the Jena Six and were blessed to try to make some type of impact in this community before things went too far."
