No, not the Sierra Sounds. The documentary was narrated by a journalist that was taken into the woods in the 1970’s and he recorded chatter (like you hear in the Sierra sounds but different) along with a lot of howls, etc. Wes started the show with this is documentary. I thought I had put on a different video entirely but after this documentary clip it went into a whole different witness account. I’m almost positive it was on Sasquatch Chronicles but I might be mistaken. I really want to listen to these sounds in my car where I have a killer stereo!
