The Grammy-winning musician has entered into a partnership with Bionic Yarn, a two-year-old textile firm based in New York dedicated to developing environmentally sustainable fabrics. In this new role, Williams is both an owner and investor in the company, as well as an ambassador and spokesman for the brand. Williams has been on an acquisition spree lately: last week, he was at Art Basel Miami, where he snapped up a work by Takashi Murakami. Bionic Yarn engineers, markets and manufactures premium yarns and fabrics using fibers comprised of recycled plastic bottles.
