Music fans who decided to check out the Roots on Day Three of the Echo Project in Atlanta on Sunday were treated to an eclectic set filled with medleys and covers ranging from Mims' 'This is Why I'm Hot,' to the diabolical Biz Markee's 'Just a Friend." Midway through the set, the hip-hop collective scaled down to a power trio for a jammed-out version of Bob Dylan's 'Masters of War.' Guitarist Kirk Douglas handled vocal duties, delivering lines like "Even Jesus could never forgive what you do" with soulful conviction.

According to frontman Black Thought, it's a song the Roots don't often perform but they felt it would be appropriate at the Echo Project, a green-friendly event with a rather pronounced tree-hugger mentality. "It was written over 40 years ago," Thought told the audience. "But we feel it's still relevant today." The performance was emotionally-charged and accompanied by massive jams.

The full Roots ensemble then returned to the stage and lightened things up with a portion of Kool & the Gang's 'Jungle Boogie,' proving that you can preach to a receptive crowd, but at the end of the day, the kids just want to dance.
