All kidding aside, I think this opens up a rather interesting philosophical discussion. What is it that defines music as being live?

Is music live because it is recorded with all musicians playing simultaneously? Does the final product have to be generated from a single take, session or performance? If there is no audience is the music still live? If an orchestra sits down in a concert hall with sound baffles in the place of the audience, are they still performing a live recording on their 5th take? How much knob twiddling, dubbing, over dubbing, splicing, and dicing can an engineer do before a recording is no longer live?

…and what I really want to know is what does it mean when a dj is going to perform a “live set”

oh! and is it possible to make a live recording of someone lip syncing?
