Army_of_One
This is an excellent mashup of two great artists who go back well over 15 years, with great verses over multiple incredible beats. This is a really great showing King, easily holding his own in friendly competition with Blu, an underground legend who's currently going through one of the strongest career renaissances that hip-hop has ever seen. I know it's not considered an EP, but if it were it would easily be the best one of this year!
