Gustav Theodore Holst (1874-1934) was a renown English composer. He had a distinctive style drawn from a wide variety of musical influences, including Wagner, Strauss, and Ravel. His best known piece is The Planets suite. While moderately successful, Holst had to balance his love for writing music with the practical realities of providing for a family. This film examines the life of the artist through the loving eyes of his daughter, Imogen. She traces her father's story of art from his father, to explore their rich family history, from which Gustav gained his most direct inspiration. This is a must watch for any lover of music, a personal and moving story of a musical innovator.
