ALFRED McMOORE
In an interview on the National Public Radio radio program Fresh Air, as reported in Wikipedia: “The group’s name ‘the Black Keys’ came from an artist diagnosed with schizophrenia, Alfred McMoore, that the pair knew; he would leave incoherent messages on their answering machines referring to their fathers as ‘black [piano] keys’ such as ‘D flat’ when he was upset with them.”
