ELI5: What do EDM Artists (Skrillex, Deadmau5, etc.) actually do on stage at their concerts? Aren't they essentially just pressing play on certain pre-recorded tracks?

That's a bit like saying "aren't baseball players essentially standing around?" At a glance, yes. Statistically, yes, most of the time is standing around. It's what happens when they're not standing around that separates the amateurs from the pros.

The set is not pre-recorded, although the songs may be. Songs are chosen by the DJ, mixed in/out, and modified in real time to be unique. Many DJ's engage the crowd and add a whole lot to their performances.

Quite a few are known for having separate vocal and music tracks and mixing them live. Some are known for performing on the mic.

Some artists even create the music live. The sample, mix, and compose live on stage. Atom and his Package springs to mind as an example.
