Let me preface this by saying all the Mad Decent label artists were fantastic; Kito & Reija Lee, HeRobust, Zed's Dead and especially Major Lazer, their set was incredible and Diplo had the energy of the crowd sky-high!
The average rating is due to the venue. Revolution was simply not prepared for an event this size. Entrance lines were upwards of 90 minutes and there was not enough staff to keep the crowds in check. Even if they didn't have enough people some barricades or proper lanes would have helped greatly.
Once inside I quickly found myself in another 45 minute line, this time for the restrooms. By my count there was eight for what seemed to be several thousand people, no separate men and women's, it was a total disaster. Aside from that, since it was an outdoor event they staged it in the parking lot and the weather being uncooperative caused several areas to be flooded, but there's not much you can do about that.
That aside, the artists rescued the event and I can only hope going forward Revolution is better equipped when handling something of this size.
