- Laurence Libin
(b Napier, New Zealand, May 14, 1946). Intermedia artist whose transdisciplinary practice includes video/sound work and installations, experimental instruments, graphic scores, and improvisation. He studied at Elam School of Fine Arts, Auckland (DipFA Hons, 1971) and the University of West Sydney, Nepean (MA Hons, 2000). Since the early 1970s his sound-based artworks have involved newly invented instruments. A member of the original Scratch Orchestra in London (1968–9), Dadson founded Scratch Orchestra (NZ) in 1970 and later From Scratch (1974–2004). A key part of From Scratch’s development was instrument invention, from using found objects to making unique, custom-designed devices. Tunings evolved from randomly pitched sounds to 12-note and microtonal tunings, and just intonation. Central to this development were tuned percussion stations composed of rack-supported, four-tiered assemblies of PVC pipes, tuned-tongue bamboos and bells (in which parallel slots cut in the materials produce a vibrating tongue matching the resonant frequency of the open or closed tubes), and roto-tom drums, combined with special methods of playing. These percussion stations, along with other novel struck and spun acoustic instruments, produced the characteristic From Scratch sound. More recent instruments include the Zitherum (long-stringed instruments that are drummed and bowed), the metal-pronged Nundrum, the stroked RodBaschet, the gong tree, Foley-trays, the Water Cooler Drumkit, water bells, the Gloop-spring-string-drum family, the Sprong family, and other fanciful types....
