I find your lack of faith disturbing: Diary of a Mad HouseJosh:
I watch Bruce Springsteen's "Making of Born to Run" documentary. The engineer from the album describes a 24 year old Springsteen standing in front of a microphone working on a guitar solo. Every time he finishes a take he turns to the engineer and simply says "Again." He does this for twelve hours straight. The recording of the song "Born to Run" takes six months. The drummer and the keyboardist quit and don't record the rest of the album. Thirty years later they asked the drummer how he felt when he heard the song today. He said "I feel like running out into the middle of traffic." He sort of laughs afterwards, says he was happy to be a part of the album, but you know the day he quit the E Street Band plays over and over in his head like a fever dream.
