Transplanted Roots 2022 is delighted to welcome Sarah Hennies as guest composer and speaker, with the world premiere of her new work Thought Sectors. Additionally, the conference coincides with two important centennial celebrations, reflecting on the legacy of Iannis Xenakis and Chou Wen-Chung. Their seminal works for percussion draw on different legacies and have deeply informed our growing sense of our artistic selves. Proposals need not refer to these composers.
