Attending a Martin Garrix concert for the first time. What to expect?

I have been a big EDM fan for some time, and Martin Garrix is certainly one of my favorites. I am from Mumbai, India, and attending his show here on 14th March. This would be my first concert by a major artist, and I wanted to get some idea of what I could expect from it. Sadly, I didn't get a ground ticket, so I'd be grabbing a seat in the stands, but I am still expecting to enjoy the vibe from there.
