While holding down guest DJ duties Thursday night on BBC 1Xtra, Jamie xx, who was filling in for resident DJ Benji B on the show, had plans for his presenting slot all figured out.  He was going to play some of his own tracks (“Sleep Sound,” “All Under One Roof Raving”), fan-favorites and welcome a surprise visit from none other than James Blake (because that’s what usually happens).

“I’ve just walked in on you playing your own song, it’s quite sweet,” said Blake as he arrived. And of course he didn’t come without bearing gifts. Before the leaving, the crooner left behind a brand new song for Jamie to debut, which features haunting production, accompanied by laser-beam shooting synths.
