doing a live set is alot easier than it used to be.
me and mikey used to break down the whole studio to go out and play live. 909, 303, monopoly, mixing desk, the works.
now I just take ableton and a couple of midi controllers and a keyboard.
for the record, if another DJ or performer is being a prick on the night, I'll confront him and if he doesn't pull his neck in, I'll knock him out.
unfortunately physical violence and/or public humiliation seem to be the only way to deal with wankers in general, especially in the club scene.
