Singing a hypnotic rendition of James Blake’s The Wilhelm Scream is London up-and-coming soul-vocalist Kwabs. The singer, whose full name is Kwabena Adjepong, first appeared on the BBC show Goldie’s Band being mentored by drum ‘n’ bass pioneer Goldie, but put up this video of him and some mates this week on his Facebook. Some of them even look a bit like the Blake himself, but what is the guy in the back playing? His chair?
