From her childhood in Detroit to her professional career in New York City, American composer Lucia Dlugoszewski (1925-2000) lived a life of relentless creativity as a poet and writer, composer for dance, theater, and film, and, eventually, choreographer. Forging her own path after briefly studying with John Cage and Edgard Varese, Dlugoszewski tackled the musical issues of her time. She expanded sonic resources, invented instruments, brought new focus to timbre and texture, collaborated with artists across disciplines, and incorporated spiritual, psychological, and philosophical influences into her work. Remembered today almost solely as the musical director for the Erick Hawkins Dance Company, Dlugoszewski's compositional output, writings on aesthetics, creative relationships, and graphic poetry deserve careful examination on their own terms within the history of American experimental music.
