I spend several days at a time without enough sleep. At first, normal activities become annoying. When you are too tired to eat, you really need some sleep. A few days later, things become strange. Loud noises become louder and more startling, familiar sounds become unfamiliar, and life reinvents itself as a surrealist dream.
I wasn't playing the music, the music was playing me... and once that went away, and I had the feeling I was playing music, I had to stop. The need to go onstage and get my brain flattened every night left me, and what I didn't wanna do is go onstage and perpetrate a fraud... You cannot fool an audience.
