Having a hard time here understanding your sound.
Up to minute 5 I was going to congratulate you on your patience and endurance of strict monotony that features only minimalistic modulation.
Also I was trying to recognize your storyboard of planet exploration in it.
When up to minute 14 there had still only been minor changes and a shift to higher and sharper frequencies I started skipping in the track only to find, that the whole of the 30 minutes was solid droning. Did I miss the described crash of the spaceship? Somehow I had expected dramatic change in tempo, modulation and expression.
After all I figured you had just slapped 5 drone studies together and given it a fancy backdrop. Don't get me wrong, I loved the sounds, but 30 minutes of it???
