Hirofumi Uchino is a Sydney-based Japanese artist who creates ‘noise’-related performances, objects and exhibitions, employing a diverse range of processes and materials. He is the founder of Lastgasp Art Laboratories, which formed in 1992 as an ‘art laboratory’ and studio specialising in sound design and the manufacturing of musical instruments, sound effects pedals and metal sculptural objects.

Defektro is a sound performance project within Lastgasp Art Laboratories. The soundscapes are produced by machines, metal sheets, noise instruments and sonic weapons before being sampled, effectively chewed up and spat out for the pleasure of the audience. Over 30 titled recordings have been released from various record labels around the world. Defektro has toured internationally and continues to perform domestically. In 2017, Defektro was invited to headline at Switzerland's LUFF event and in 2024 toured Japan with the NSW government's support
