Synths and other instruments are expensive here. But you have a old P C computer and a nice microphone. You record yourself talking singing, screaming, making beatbox noises whatever your throat can do. You then manipulate the recordings to create a crazy sound collage.
You burn CD's of these recordings and trade them to the folk of Bubbling Vomit Land for supplies. You live for free, get free food and basically everything else that can be had in this corner of nowhere in exchange for your transformed mouth music. You still hate this place but at the same time you are very happy here where your name is so big. You are flinging CD's across the mote of burning puke to the outside world and drugs and other goods are being sent back. Your a hit!
