True story, in high school I went to a percussion camp where the staff woke us up with drum corps every morning. Very loud, and also very motivating!
hah! I had an old Miles Davis record I would fall asleep to. The tune Blues for Pablo had this incredibly loud part, then immediately would be almost silent. Took me a while to realize what was happening… that loud part would wake me up, scare the crap out of me, but by the time I sat up in bed, the music was calm and quiet.
