Sigma Sound is opening its doors for very special occasion this evening. The Roots’ Black Thought a.k.a. Tariq Trotter will be rallying folks for the Let’s Move It Philly! charity concert, which is held annually to raise funds for his GrassROOTS Community Foundation to benefit poor women and girls. According to AllHipHop.com, this year’s event will also help to bring awareness to childhood obesity in the African American community. Black Thought is scheduled to perform sets with his music brethren ?uestlove and Money Making Jam Boys. Pals Nikki Jean, DJ Rich Medina, and DJ Diamond Kuts (Power 99’s Nikki Minaj) will also be donating their time and talents. The Carson Valley Children’s Aid will be providing additional health services with free HIV testing and other health-oriented activities happening throughout the event where you’ll find participation from State Representative Tony J. Payton Jr. and Mayor Nutter (who most likely will bust-a-move or a rhyme to “Rapper’s Delight” before the evening is over). It’s a good time for a good cause! Sigma Sound, 212 N. 12th St., 8pm, $30 adv/$40 door, 21+ – H.M. Kauffman
