it sounds like a tom morello overdub or something to me but I hear the noise. It sounds similar to when that noise comes through your speakers right before the cell phone rings but more focused. It is very faint but it sounds like a screechy guitar with flange being kill-switch toggled to death with a touch of the raspyness from the jambi solo if that makes any sense.
I have also heard something similar to this on the led zeppelin BBC recordings, so it is probably just a Live recording thing that has to do with the quality of the recording itself. In other words the integrity of the recording is being compromised by the lack of quality equipment and recording technique that leads to that faint sound we are hearing.
Tool FAQ "If you're wondering about "Cold and Ugly": the original theory was that during this live recording, some guy with dreadlocks kept blowing an air horn, forcing the band to start over. A telephone hotline takes credit for this; it may have been Maynard kidding around with the singer from Green Jelly."
This may nit belong here since I didn't go back to listen to what your talking about, but no one eles posted it and it might be helpful.
