By ambient group Igneous Flame.
I once made the mistake of playing one of my ambient discs in the car when I was driving my father somewhere when his car was in the shop. The first track came on and he started squirming and appeared to be straining to hear something. After a minute he asked "What the Hell IS that?" I answered "It's my music." He replied "Music? I thought something was wrong with your brakes."
