The different pieces, which include video and audio production, of Alejandro Garmendia and his collaboration with Nicolas Persheid, as well as his audio work alongside Michel Ugartemendia and other productions, are together in this site due to the common nexus in their use of the modification of the gravitative parameter and its visual consequences, based on the gravitative function as a perception factor. This series of works presents a common factor and origin in the dialogue between the intention and the strategy that in the case of images and video, works as a generating factor based on the modification of one and the rest of its parameters, causing the rupture of the logical connection between the events suggested in one image. In the Sounds, Garmendia adds the gravitative parameter and the orbicularity to experiments carried out by other electronic artists within the context of electronic generative music, which, in the context of video gravity, includes several collaborations.
