Composer, writer, and musician Paul D. Miller's multimedia performances, recordings, art installations, and writings immerse audiences in a blend of genres, raising awareness about climate change, sustainability, global culture, the role of technology in society, and other pressing environmental and social issues. His multimedia composition, book, and installation "The Book of Ice" creates an experiential visual and acoustic portrait of Antarctica's disappearing environment. In "Nauru Elegies," he explores, through a string ensemble, video, animation, and live Internet feed, problems facing the environmentally exploited South Pacific island of Nauru. He also founded Vanuatu Pacifica Foundation, a sustainable arts center on the island of Vanuatu. Miller first rose to worldwide fame as hip-hop turntablist "DJ Spooky" and is now a sought-after lecturer and performer at prestigious venues, arts institutions, and universities on every continent. His free, open-source iPad app, DJ Mixer, has been downloaded over 20 million times. It gives users DJ tools to mix, scratch, and add electronic effects to tracks from their own digital libraries. He was the first artist-in-residence at New York's Metropolitan Museum of Art.
