Run The Jewels are making great waves across the Atlantic, but had yet to truly hit UK shores with any force until last weekend. The hip hop duo, explosive and intimidating onstage, incredibly laid-back off it, set West Holts ablaze with a series of gut-punching beats, flawless technical ability, and politically-charged lyrics. El-P and Killer Mike are both 40 years old, but bounced around the stage like a duo half their age, spitting out furious tracks such as 'Oh My Darling (Don't Cry)' with the characteristic enthusiasm of Glastonbury debutants. They'll have secured an army of new fans this weekend, and are worthy contenders for the best hip hop set of the festival - even eclipsing the gargantuan Kanye West. More on him later...
