The soulful voice of Ray Charles offers up a throat-tightening melody as dancers' movements respond to the specter of Hurricane Katrina in a piece called "Sincerely Katrina Jones." Such emotive pieces abound in the Juneteenth/Houston Black Dance Festival, a showcase of African and African-American dance, and a benefit for Katrina victims. Watch for funky works such as "Street Mix" by local troupes like City Dance Studio. Another can't-miss: "Econ Con," a traditional dance performed by the Senegalese troupe N'Kafu Traditional African Dance Company. The tribal, hip-hop, modern jazz and other genres represented here promise to raise your awareness, raise your spirits and raise your butt out of your seat. Festival begins at 8 p.m. today.
