Rapper/actor Mos Def and singer Goapele are joining forces in the name of science for an innovative presentation on Sunday, September 5th at the Chabot Space & Science Center in Oakland, California. Goapele will be on hand to handle hosting duties at the I.S.I.S. Science & Culture Festival, where NASA will unveil its first-ever holographic presentation featuring holographic images of Mos and astronaut Leland Melvin. The purpose of the free event is to encourage youth to embrace "Science, Math & Discovery." Check out the video below for a sneak peak at the project and to find out why Dante feels it's important.
