The stage set up was amazing with him performing on top of a large head structure. The sound and lighting effects were wonderful especially with the colours and L.E.D. display.
I personally don't like his sound of dubstep/house as I think it is pre recorded to match the lighting effects. But in terms of an overall performance it was great. The crowd really got into it.
You can see a clip I recorded of his most famous song, Levels, below.
