Patrick Feaster and I were talking about recordings in which people imitate animals (specifically, we were listening to The Pussy Cat Rag on the National Jukebox), and I remembered field recordings in which real animals have been audible. I've heard a dog yelping on a recording from Nepal (and the ethnomusicologist saying, "Damn dog," suggesting that the animal had been interfering with the equipment). Also, a recording of folk songs in the US, in which the elderly singer was accompanied by his squawking parakeet.
Patrick suggested that we could call these "phonobombs." Has anyone else heard things like this?
