Killer Mike and El-P (formerly of Company flow) aka Run The Jewels are an unlikely paring, Killer is from Atlanta and is a member of the Dungeon Family and El-P is from Brooklyn New York and was a vital piece in the Rawkus records empire of the late 90s and early 200s. The Dungeon Family were crucial in developing the sound of Atlanta and the south and Rawkus was crucial in the development of the east coast sound aka the boombap. The 2 sounds were different but what is the same is that both coast spit dope lyrics and had a great live show which is really all you need. The unity of these 2 underground kings is a great thing for hip hop. The 2 have done all the major music festivals and have one of the best live shows in hip hop. Check this video as the proof.
