The Indian Sonic Research Organisation is a collective dedicated to the proliferation of creative music and experiments in sound. We are instrument builders and artists. Our performances incorporate DIY and home-made instruments made with discarded electronics and other found objects. We also run a community music lab and record label which disseminates works by Asian composers, sound artists and musicians.
