Just arrived at my first gig of the night and the green room is a sectioned off area of a warehouse floor which is usually an “Adventure Sports centre” so it’s nightclub lighting (black light, laser chasers, flashing RGBs etc) and the music before the show is at nightclub volume, so I’ve just had to walk out and stand in a stairwell. The promoter came and tried to tell me something and I had to tell him I couldn’t process hearing him at all, and then I had to walk out.
