Drake & “40.” Jay & Tim. Chance & Nate Fox. Kevin Abstract & Planetarian? That’s right (sorry this is cheesy); the two 17-year-olds have thrown their hats in the ring for the best rapper-producer pair of the year. On the Kevin Abstract EP Kevin waxes some deeply personal anecdotes about himself and his family, while Planetarian (under his HoraceTheGiant production moniker) provides jazzy beats featuring exotic instruments and hazy experimentation. The result is one of the best EPs of the year.
