You mean this mindfields-like synth-sound fading in the background from the left to the right?
The drumroll from Breathe was used here as well.
Then there's this typical sixteenth parts synth (pretty much like that in Firestarter), his Sp1200 Drummachine spitting out the bassdrum again, then portions of the army march-intro from the live-show that someone already mentioned in the BGAT-threads.
The Boss SE70 does some distortion again and it really might be Keith plaing the guitar, because it's a) a very easy guitar-line and b) not comparable with any other style of any dude having played on previous albums. Just a presumption though.
More echo and reverberation fx than in most Prodge-records.
The bass does that (not so cool) chemical brothers-like sixteenth part 'on the measure'-repeating (Compare music:response) and my favourite part still kicks off at 2:56, where the "rohypnol" cut's it's way through and turns itself into the right direction.
At 3:49 those very nice squeeky distorted vox are brilliant again and we get proper chord changes! At least! it seems I'm really going to like the instrumental a LOT more than the original (which I liked very much already).
