A French perso... | In France we have this saying that if you sing badly it will produce rain. More precisely if you sing out of key, or pitchy, then you'll make it rain. "Cacophonix" means "cacophonie" which is French for "cacophony": harsh discordant mixture of sounds. Thus triggering the rain. |
