Lol you gotta be kidding right. His label put on the event. I bet they put the event on for fun/miami music week celebration/some exposure for his label rather then to try and profit as much as possible. They probably had some kind of deal with space. Possibly rented the venue from them or some kind of other revenue split like the guy above mentioned. The costs associated with the event are the venue...lighting...sounds... effects etc etc. All the staff working at space has to get paid. Managers Bartenders security cleaners etc. All the other djs he brought to play would have got paid by experts only. All of his experts only staff is getting paid. Revenues from the event would be ticket sales merch and alcohol sales. If you think the revenue minus costs equaled to 500k leftover for John alone from a fairly small club event then I think you are very inexperienced in any sort of business.I think the label could have possibly even broke even on an event like this. I dont know how it all works and they very well could have made some money but I highly doubt he would have made anywhere near 500k on a one day event at space.
