as a producer, with live pa i think you can take more risks than you can making records. if you produce only with the intention of pressing records, you have to worry about whether or not a long line of sober people (record co, distributor, djs...) are going to be willing to spend money on it after listening to it over and over. but if you have only the dancefloor to worry about, where you have a captive audience listening for the first/only time, you can do almost anything you want.
