Classically trained, Lansley performed at the Royal Ballet before seeking a new way of using her art form to make a political stance, something she described as becoming a 'speaking dancer'.
[2][better source needed] In 1972 Lansley began choreographing for Richard Alston CBE's Strider dance company.
[3] In 1974-1977 along with Sally Potter and Rose English, Lansley co-founded Limited Dance Company with a focus on performance based art.
She also worked on several feature films as a choreographer and performer directed by Sally Potter including Orlando, The London Story, The Gold Diggers and The Man Who Cried.
[4] The studio has supported the development of her key works: Holding Space (2004), View From the Shore (2007) and Guest Suites (2012) - all performed in the Clore Studio at the Royal Opera House - Standing Stones (2008, York Minster, and UK cathedral tour) and About Us (2019) in partnership with Modern Art Oxford.
