Marcos Díaz has been part of Buenos Aires underground for many years, being in projects like Bosques and making solo music under the pseudonym Entidad Animada (animated entity). Under this project, Marcos has explored sounds that involve a mix of feedback/distortion through synthesizers, guitars and drum machines that hint at the influence of Stereolab, Spacemen 3, and mid-nineties shoegaze. However, there are also ambient soundscapes with a slight rubbed of the ritualistic psychedelia of the Popol Vuh. The display of colours in his music comes together in the midst of a playful, relaxed and optimistic environment that is simultaneously melancholic. Because of the nature of those pieces, but also because in Entidad Animada there is also space for collage sounds that blend randomly with textures of a primitive analog sound, which inevitably causes a paradox between what is alive and what is inert. And it is because Entidad Animada is precisely that, a spectrum or a vision, a ghost. And these sounds are proof of his existence.

Pruebas de existencia (proofs of existence) is a collection of recordings that Marcos has made in recent years and that we have selected for this album, his first work on Umor Rex. A couple of these pieces were only released digitally, while the others have been on ltd cassette editions through Fuego Amigo Discos in Argentina. Pruebas de existencia is an Umor Rex compilation and remastered edition.
