Excerpted from The Producer: John Hammond and the Soul of American Music, by Dunstan Prial

On a cold, clear night in February, 1933, Hammond went on the town alone in search of music. Heading up Broadway toward Harlem in a Hudson convertible (he kept the top up in the winter), he fought traffic, but as he passed Columbia University, he was flying. At 133rd Street, he took a right and headed east toward Lenox Avenue. He pulled over after a few blocks and parked in a space a few doors up from a new speakeasy run by Monette Moore, the singer who had appeared with Ellington and Carter at the fund-raiser for the Scottsboro boys he had helped organize the previous fall.
