Muneteru Ujino is renowned for his "sound sculptures" — art objects for which sound is integral. He often experiments with home appliances such as lamps and electric drills, and his combination of art and music has led to comparisons with Luigi Russollo, the Italian painter and composer whose experimental "noise music" inspired aspects of the Neo-Dada visual art movement of the 1960s.

Ujino collects scrapped and waste items and breathes new life into them by turning them into artworks. His installations appear to warn viewers of the world's reckless pursuit of mass consumption — its potential to continue and the consequences if it does; till July 15.
