I've said it many times before, but how anyone could fall asleep during ( ) is beyond me. There's just so much there for your attention. Just the same, I tried driving to that album once and it put me in a trance and when I came out of it I realized I had driven 20 miles in no time at all and I took the CD out.
I often fall asleep to either Waker by Disasterpeace (which is free) or the two quieter tracks from Molotov and Haze by Bass Communion.
