Whenever I indulge in a new genre that I know nothing about, I do what I did here. I typed up Dubstep on Youtube and listened to about 2 hours of Skrillex. I fell asleep to it in the coffee shop so that I could absorb it in more depth...and catch up on a few zs. There's no better place to sleep than a public coffee shop cuz your wake up coffee is right there waiting for you. Not knowing how Dubstep sounds are made, I had to make up my own which included my microwave for the desert scene and I screamed a lot for the eagle sounds. I'm sure my neighbors appreciated that.
