Thank God that nothing's happening in this thread at that time this afternoon, eh?
A very special (and by special, I mean very much in the "needs" sense of the word) recording is hidden in one of my posts on GRcade. Using the special photographic clue already present in this very thread, you may well be able to work out what the recording is about. That will lead you to a specific word you need to search for, under my username.
In one specific word in one specific post, the file resides. And that post probably isn't from the last few days.
GOOD LUCK. It would be absolutely terrible if you didn't find it.
