EDIT: a lot of people have written in asking what exactly my vocoder setup is. Well that's your classic Roland SVC-350, and I'm using a Kurzweil K2600 with the basic jar-of-wasps analog brass sound as the driver. The vocal mic has no pre-processing whatsoever, I just plugged it directly into the vocoder.
