Maryland based duo Collectible Humans just released their debut EP String Theory, and we are getting a real treat here. 7 tracks of headnodding beats from Adam Selene with introspective lyrics delivered with nice flows and a lot of attitude. We might not hear anything new here, but we are however getting straight up hip hop without a lot of gimmicks or silly posing. And sometimes that's just what you can really ask for. Want to check it out for yourself? Go to their bandcamp page and download the EP for free.
