Do prison guards count? This is on the extraordinary Syliphone label out of Guinea but apparently "Boiro" stands for Camp Boiro which was a notorious torture prison. There's a book by Adolf Marx where he describes his imprisonment and torture in said camp in which he describes hearing the guards meet and rehearse.
So it could be that the guys on this record took a quick break to lay down some vocal harmonies and entwine around them a gently optimistic organ part... and then went back to thumb-screwing helpless prisoners and clipping electrodes to their balls so they could mutilate their genitals with electricity? Fucking hell. That's quite a thought to process isn't it?
I guess there is no reason why an "evil" person shouldn't have any particular talent. However, it's one thing to see a torturer, say, playing football or being good at, I dunno, chess say - but I think that we often share a sort of unspoken (and no doubt stupidly naive) assumption that art and other types of creativity somehow reflect or represent the soul of the person who made it. It can't be just me who struggles to picture someone who could cruelly and mercilessly torture a fellow human being, and then walk into a different room and lay down some heartfelt vocals on a haunting and beautiful song about loss that captures the imagination of almost anyone who hears it and reduces most to tears.
