This mixtape from Chicago-based artist Chance The Rapper is pretty amazing. It may not sound like much the first few times you listen to it, but after the third or fourth play through, the personality and sound of all the songs really grow on you and you can't put this album down. I highly recommend this album to anyone who likes chiller hip-hop, experimental songs, and weird beats.
