i want to break it

i have never finished a single track, but im a devil when it comes to improvising and preforming live,
why i have never finnished a track is probably becasue music is a very direct thing for me, and i easy get boored whit my tracks when i sit down and program and want to move on to the next thing,
i recently had a gig at a art show where i improvised for 6 hours non stop,
i went there whit just a few bars in my bagage to build upon, but it went great and people loved it.
now im having another of them art shows comming up where ive been asked to play.
this one is gonna last for a weekend and will be open all night,
and i was thinking this could be a good time to try and set a world record.

edit- never finnished a dubstep track i mean, ive finnished tracks before.
i have been in the electronic music scene for some time, but dubstep i have only been doing for 7 months or so.
