“Mr. de Groat was a significant presence on the New York downtown dance scene and in Paris in the 1970s and ’80s. Introduced to audiences through his work with [Robert] Wilson, he later formed his own company and built a distinctive choreographic identity through his use of spinning, a technique he began to develop for Mr. Wilson’s work.” — The New York Times
