Watch FilmoFlix. Mound is a celebration of the moving painting, in which more than one hundred pallid puppets – clowns, spectres, gnomes, wraiths, and ghouls – writhe, sway, plod, and transform with awkward grace to the mournful musical accompaniment of It’s Raining Today(1969) by legendary singer-songwriter Scott Walker (also known as Noel Scott Engel).
