10 Rappers Turned Social Activists at HotNewHipHop.com
#3 - Kendrick Lamar
In addition to empowering young black folks through his music (and his performances - that Grammy performance - my God), Kendrick has quietly donated hundreds of thousands to the Compton school district for music, sports, and other after-school programs. He's even used his endorsement deal with Reebok to bring about a detente between Bloods & Crips. For his efforts, Kendrick was bestowed Compton's key to the city in February.
