Hmm... hard to say, since an EDM Dj presentation per se does not go over 3 hours tops, but in most venues they will start playing well into the night, usually starting around 11pm. You are better off calling the venue and asking how long the opening act lasts and about what time will he perform, then add some 3 hours to that.

I went to Axwell's presentation some weeks ago and it began at 11pm and was over at about 3 am.
