University of Bristol, where he developed his interest in electronic music. He became a pioneer user of analogue synthesisers, notably using the
EMS VCS 3, three of which were used by his 1970s touring band, “Uncle Jambo’s Pendular Vibrations”.
Life on Earth The BBC's
Life On Earth documentary, first broadcast in 1979, heralded a new genre of nature programming, and the avant-garde and pioneering music was pivotal to the programme's impact. During the composition for
Life on Earth, Williams mentored the film composer
Martin Kiszko who then assisted him. (
William Goodchild was a subsequent assistant). Following its success, Williams worked on the soundtrack for the three-part ecological series “Earth” for
Thames Television and a series of

Goya,
Gillray,
Mary Wollstonecraft and
