G Herbo is back and with a project for his hardcore supporters this weekend. The Chicago drill stalwart left off Greatest Rapper Alive, a 16-song effort with one feature (Big Opp) and its executively produced by Oz On The Track. The catch though is that it's only available on his new self-titled app. It's available for download on the App Store or on Google Play, however, it's a little tricky to find on your mobile device. You might have better luck though, so visit the rapper's website here and give it a shot.
