Here is a young lad that I had the pleasure of seeing live at the Grammy GPS concert at the Hi-tone a few months back. Gavin "Cities Aviv" is gaining attention in the underground hip hop community as well as the indie labels. He even had a positive review on Pitchfork, which is to say a lot. He was excellent live, and had every dirty hipster up in there bobbin' their heads. Check out his music here or in my earlier post.
Another young artist worth a listen is local hip hop artist Skewby. He is only 21 and has already accomplished artistic feats such as opening for the Lil' Wayne Farewell Tour and being dubbed as the "New Memphis" and a reviver of "real hip hop" in the words of blog Ill Roots. Here is a music video that pays an homage to Memphis and it's hip hop community. Represent!
