I don't think that link is working... or is it?
Or maybe it even shouldn't since the site closed.
There has been some smaller elma videos here but I cannot recall hearing that one specifically.
it was some sort of russian site, I recall to have seen unrealeased-otherwhere small elma videos - some weren't elma at all, but just real life imitations of elma; like a guy stunning on his bmx, he miss the gap, but this one wasn't wearin' any helmet
