Max Eastley (born 1 December 1944, Torquay, Devon, England) is a British visual and sound artist. He is part of the Cape Farewell Climate Change project. He studied painting and graphic art at Newton Abbot Art School and then went on to gain a BA in Fine Art (1969–1972) at Middlesex University (formerly Hornsey School of Art). He is a sculptor (kinetic), musician and composer. His primary instrument is a unique electro-acoustic monochord, developed from an aeolian sculpture. 'The Arc' consists of a single string stretched lengthwise across a long piece of wood (around ten feet) which can be played with a bow, fingers or short glass rods. The end of the instrument has a microphone attached so the basic sound can be amplified, recorded and run through sound effect programs.
Eastley has collaborated with many different artists and musicians on performances, installations and recordings including: David Toop, Brian Eno, Paul Burwell, Victor Gama, Hugh Davies, Steve Beresford, Peter Greenaway, Dave Hunt, David Buckland, Evan Parker, Peter Cusack, Spaceheads. From 2001–2002, Eastley was a visiting fellow at John Moores University Liverpool and is currently (2010 onwards) an AHRC research fellow at Oxford Brookes University researching Aeolian phenomena. On 17 May 1989, Eastley was awarded a prize in the 'Learning Spaces Category' of the working in the City European Communities Architectural Ideas Competition (University College Dublin).
