[2] After being introduced to him by his dentist,[3] in October 1975 he was invited to accompany walking artist Hamish Fulton on a journey through the Canadian Rockies which he describes as seminal in his transition from traditional sculpture and portraiture to environmental or land art.

[3] Drury has largely continued to eschew traditional larger galleries, preferring to distance himself from commercial expectation and production which has allowed him a freedom to work in remote areas and in natural surroundings and to make art in a wide range of unusual collaborations.

He has made several around the world, with his latest, Horizon Line Chamber, constructed with master craftsman Andrew Mason, opening in 2019 at Morecambe Bay as part of the Headspace to Headlands Heritage Lottery Commission.

[7] On paper, he uses a variety of unusual media, notably mushroom spore prints, dung, and peat, as a source of colour and patterns, which he might overlay with text or fingerprints, or underlay with maps or other geographic images.

[2] Drury is an active participant in several organisations which aim to address the effects of and challenge thinking about climate change through art, including Cape Farewell, UK,[8] ONCA[9] (a Brighton based charity which "supports artists and audiences to engage with environmental and social challenges" and Art Works for Change, which creates exhibitions worldwide to advocate for human rights, social justice and to highlight environmental awareness.
