James Blake's songs are so simultaneously delicate and heavy they could quietly crush your heart with poignant chords. But "CMYK," with its R&B vocal samples, takes that concept even further: a sped-up Aaliyah patched in with a synthy beehive sounds even more plaintive, and when she wonders if I let you know...?, it's less of a question than a statement she knows the horrible answer to. What kind of tragic life has James Blake had to know all this? Do you see his cherubic mug above? Isn't he like 12? How did he get so brilliant?
