Half the musical ideas I've had have been accidental. The first time I discovered backwards guitar was when we made Rain. This was a song I wrote about people moaning about the weather all the time. I took the tracks home to see what gimmicks I could add, because the song wasn't quite right.
I got home from the studio stoned out of my mind on marijuana, and, as I usually do, I listened to what I'd recorded that day. Somehow I got it on backwards and I sat there, transfixed, with the earphones on, with a big hash joint. I ran in the next day and said, 'I know what to do with it, I know... Listen to this!' So I made them all play it backwards.
I wanted to do the whole song backwards. We ended up with a bit of the voice at the end backwards and half the guitar backwards.
