As far as I know this event is not all access. Mark Oliver is playing an all classic set in the main room and the Industry party is in the Kool Haus. Sometimes they do give wristbands between the two rooms but considering there has been no reference to this I would think that you have to choose one or the other.
That being said, I was wrong once before back in '97 so don't be mad if this information is incorrect!! I am basing this on the Guv website and the fact that the Industry reunion has been advertised by itself for a while now.
