His oeuvre takes on multiple forms and expressions.
Intermedia art covering the scope of audiovisual performance, electro-acoustic and symphonic music, conceptual art, installation as well as film. Also an essential part of his artistic output comprehends the affinity for writing.
Focussing on the recurrent Why behind the mediums, his discourse is triggered by the most essential contiguity where thoughts, emotions and aesthetics converge and blossom.
Comprehending Art as autopoietic and unique instance, Mejía defends vehemently the idiosyncratic idea of reaching "Absolutism" and holism through Art itself. This is considered as the end result of the act and practice.

A plane where minimum and complex coexist, an all-embracing art form.
