"It's amazing all that you have gone though getting ‘experts' to analyze those voice recordings. They are so sensational! I've listened to the CD at least forty or more times. And I play it for anyone who will sit still long enough to hear it. To me, it is as convincing an argument for the existence of the creatures as the Patterson footage is. The CD itself is a masterpiece! The story is great! The music is great! The content is great!"

The sounds, vocalizations, that include whistling, have been professionally analyzed and it is the belief of the scientists who did the analysis that they are not man-made. Regardless of the findings, which incidentally have never been disproved- I am satisfied and will personally vouch for the integrity of both my associates, Alan Berry and Ron Morehead, in the matter of these recordings. Indeed I look forward to working with them again, in the Bigfoot field, in the future."

“I heartily recommend to serious Forest Giant researchers that they obtain and review The Bigfoot Recordings by Sierra Sounds. While I was not “on site” when these recordings were made, nor have I personally met any of the persons involved, and while the greater parts of these sound bytes contain vocalizations that are beyond my personal experience. 1 still can state that this finely produced recording indeed contain segments that I have heard when I am certain I was having an encounter with these elusive people they call Bigfoot. For me or anyone else to dismiss these recorded sounds as being inauthentic because we have not heard them would be unscientific, arrogant, and foolish.”
