The so-called sound art project known as Nocturnal Emissions take a few bland self-help samples, lay down a simple groove and deliver an anthem of sorts on the theme of healing. Because by the time 1985 hit, everyone knew someone who was dying of the big disease with a little name (as Prince put it), even if we didn’t actually know they had it yet. Such was the AIDS crisis of the mid-80s — a death sentence all the way. And yet we’re human, so we never give up. Some of us anyway.
