Louis Thomas Hardin, known professionally as Moondog, was an American composer, musician, performer, music theoretician, poet and inventor of musical instruments. Largely self-taught as a composer, his prolific work widely drew inspiration from jazz, classical, Native American music which he had become familiar with as a child, and Latin American music. His strongly rhythmic, contrapuntal pieces and arrangements later influenced composers of minimal music, in particular American composers Steve Reich and Philip Glass.
