will.i.am's annual pre-GRAMMY charity concert featured veteran rap stars like Slick Rick and Doug E. Fresh, Bell Biv DeVoe, Chaka Khan and Sergio Mendes.
The "Trans4m" event raised more than $2.4 million for the rapper-producer's i.am.angel Foundation. The group provides educational support for students in the underprivileged section of East Los Angeles, where will.i.am grew up.
"People are coming to the GRAMMYs just to celebrate, and when you put purpose in the room, people inherently, they want to do good", will.i.am stated. "I think that's the reason why we've been able to keep this going".
