For over thirty years, besides making music, David Byrne has focused his unique genius upon forms as diverse as the archaeology of music as we know it, architectural photography and the uses of PowerPoint. Now he presents his most personal work to date, a collection of drawings exploring the form of the tree diagram. Arboretum is an eclectic blend of science, automatic writing, self-analysis and satire. A journey through irrational logic - the application of scientific rigour and form to irrational premises, proceeding from careful nonsense to unexpected sense. The tree diagram is a form that might reveal more about yourself than you dreamed possible.
