The present work studies the scenic realizations of the ensemble called Lumínico (Rodrigo Sigal and Alejandro Escuer) from the perspective of intermediality, performance theory, musicality, and theatricality. Lumínico's proposal offers, as sound and audiovisual artists, an alternative to the experience of the traditional chamber music and electroacoustic concert, both to themselves and to the audience. In the field of music, it blurs the binary distinction between artistic work and audience by transferring the creation of the uninterrupted concert to the very moment of its execution and reception. This way, a Lumínico concert generates a unique, unrepeatable, and ephemeral event that emerges thanks to the characteristics of the scenic realization, starring the ensemble members and the audience.
