Emerging during the mid-'10s, South Londoner Fekky quickly established himself as one of UK rap and grime’s most exciting MCs via some scintillating live shows. Featuring multiple A-list guests, this debut channels the intensity of those performances. Alongside Skepta on “Way Too Much” and Giggs on “Gossip,” he proves he can fire out standard-issue chutzpah with the best of them. But Fekky’s most engaging when he sidesteps bravado, whether he’s calling out keyboard warriors (the woozy “Cappin’ on the Net”) or escaping the perils of the drug trade for musical success (the UK garage-inflected “Avirex”).
