Childish Gambino aka Donald Glover performed at 2011's Comic-Con in San Diego, CA over the weekend. The Cali rapper, along with DJ SoSuperSam, debuted a new song during his performance at House of Blues. Though Gambino didn't mention the name of the tune, it will most likely appear on his forthcoming album, which is expected sometime in September. You can check out video of Childish performing the new track below. As you can see in the clip, Glover also states that his work on the new LP is why he hasn't updated his Twitter & Tumblr in awhile.
