"Although I have no direct knowledge, early photos and self-portraits of Holtzman show him as somewhat romantic in appearance, then dapper, energetic, proud and lively. Mondrian was among the first in Europe to write about the importance to modern culture of black American jazz and its dances, which he thoroughly enjoyed until the end of his life. In Paris he had a large collection of jazz discs. On the night Mondrian arrived in New York, I introduced him to the boogie-woogie piano music of Ammons, Johnson, and Lewis. His response was immediate, he clasped his hands together with obvious pleasure, “Enormous! Enormous!” he repeated. He often went with me and others to enjoy what he called a “dancing party.” Nobody has ever written more brilliantly about the symbolic ambiance of the night club. (“Jazz and Neoplastic”,1927)."
