The creepy-ass song at the end

I "enjoyed" this documentary. The foreboding feeling kept growing as it rolled along, and that droning (?) distorted soundtrack was quite effective. But it wasn't until the very end, when that "song" started playing over the closing credits that it really got under my skin. What was that? Imagine a male/female duet sung by two shuffling zombies over an electronic drone. Lionel Richie & Diana Ross or Elton John & Kiki Dee this certainly wasn't. I had to laugh because I realized how much in control the direction of this film had. Last couple of times I got this dark, creepy feeling via film was when I watched the found-footage film LAKE MUNGO and the fright-flick THE PACT. All of these are streaming on Netflix, just so you know.

Sweet dreams...
