For the latest instalment of our RWDmix series we asked one of London's most exciting hip-hop producers, Sumgii - whose production credits include the likes of Cult Mountain, Problem Child, Piff Gang, Dream McLean, Milkavelli and LDZ - to come through with a mix of the stuff he's currently into, as well as kindly blessing us with a bunch of exclusives and stuff he's been working on that we can look forward to hearing more of in the new year. "There are probably a few tracks on here that will get me told off," he admits.
