“Mingus packed his music so full of life, so full of the noise of the city, that thirty years in the future someone listening to ‘Pithecanthropus Erectus’ or ‘Hog Calling Blues’ or any of those other wild steam­rolling things wouldn’t be sure whether that wail and scream was a horn on the record or the red-and-white siren of a prowl car shrieking past the window. Just listening to the music would be a way of join­ing in with it, adding to it.” (From But Beautiful: A Book About Jazz by Geoff Dyer)
