Cy held close a small core of deep friendships, but his uniqueness captured the hearts of many beyond that inner circle.

Cy held close a small core of deep friendships, but his uniqueness captured the hearts of many beyond that inner circle. His singular sensibility and aesthetic perspective permeated all aspects of his life, and his deep, broad creativity found expression in songwriting, textile and fashion design, storytelling, and drawing.

Cy’s belief systems overlapped in a personal and fascinating way, making this life on earth seem like a small step along a much larger path. He grew in acceptance, resolve, and strength. He was a beautiful soul, and we love and miss him very much.

In closing, Cy would want us to send a special thanks to Michael.
