A guy who needs no introduction, right? Jamie XX played "Sleep Sound" few months back during his mix for BBC Radio 6 and I think the track kinda leaked back then, but now he has released the official audio as the B-side for his upcoming 12" single "Girl" (out may 5th).
The situation which this track paints in my brain is the end of an open air when people finally start to feel that sweet exhaustion. As spring blooming around where I live, the topic of open air severely dominates conversations, so I guess that might be the reason for this association? I hope you enjoy the obscurity of "Sleep Sound"!
