make the playlist auto timed start 30 mins before curtain up, set the volume in the cue to a level suitable for an empty theatre.
Make a level change subcue (as part of the playlist cue) to increase the volume over 30 mins to the level required for a full house.
Then you can go to the bar and leave it until a few mins before curtain up!
