I want to thank everyone that has emailed me and given advice on the recordings that we did here in Iraq. Most were done in one take, due to the Helicopters and planes coming and going. We also had time restraints and had to record late into the night/morning. 
I am new to recording and mixing. Is there some kind of trick to using compression?
I have heard some tracks from others where you can hear each instrument clearly. When I start putting all of the instruments together I get a jumbled sound. Is there anything I can do to get more separation?
