James Blake live feels jazzy. What is definitely the product of many hours in front of a computer screen (plus probably a couple at a piano or with an M-Audio keyboard on his lap) gets translated into something lively and a little groovy, even, in performance. "The Wilhelm Scream" is a dreamy track from his debut label, due next month in the UK (still no US label!). If you happen to be in London, Blake's official coming out is tonight at Brixton's Plan B. It's long sold out, but there's bound to be emotional scalpers.
