I remember hearing some recordings of supposed Bigfoot sounds a while ago and it was some freaky shit, I can't remember where I heard them but I think they were similar to the sounds in the video below, only louder.
Looks like the videos done the rounds but I thought I'd post it anyway, Bigfoot's one of my fav subjects and I gotta catch em all.
It sounds almost artificial to me, but I know when I hear strange animal noises I get a case of the unbelievables.
