In 2019 the Swedish organist and composer Gunnar Idenstam was commissioned to provide the music to a film, The Vegan Toothbrush, by the Norwegian film-maker Trygve Luktvasslimo, which takes seriously the issue of climate change itself but satirises the quasi-religious intensity of climate activists. Idenstam is one of the few remaining organists who maintain the centuries-old tradition of improvisation at the console, and his extemporisations for the film, all of which are concerned with water, developed into a kind of powerfully atmospheric sea symphony.
