A burglar near the end of the century hears a song thrush on trumpet. William Blake, senior citizen of Lambeth, is walking through the Brixton riots. Garden design encodes aesthetics and slavery. This is our poetry. It ranges from archaeology to jazz, from genetics to ZAP vectors via Paxton and Mandelbrot, a performance in time. Allen Fisher's epic Gravity is an alphabet of procedural poems, a conceptual cinema, a fun-park, and a museum of anthropology. Deliberately imperfect, democratic, non-totalising, vivid and beautiful: we could not have imagined it without him.
