SIrius was born in 2008 upon the initiative of three composers: Alfonso García de la Torre, Ignacio Monterrubio and 　　Guillermo Lauzurika, who decided to join forces and form a group in which electro-acoustic music could be performed live by interacting with other artistic disciplines, a group in which every member could respond to the others’ proposals in the way in which a jazz band functions, for example. 　　The creation is defined in rehearsals, where we play, respond, improvise and interact with what the other group members are doing, be they sounds, images, movements, words or light. Sometimes we start from earlier ideas, yet other times we simply play. All the rehearsals are recorded, so that we can later select what works and eliminate what doesn’t. We talk, arrange the material and define the composition and the action. Thus, improvisation plays a significant role, both in the work’s creative process as well as its performance in public, since despite the structure’s closed nature, the tempos and development of the action are open-ended. 　　Hence, the origins of projects such as SIRIUS (2008), which was produced by and premiered at the Vitoria-Gasteiz Contemporary Art Museum (ARTIUM), where video-jock Gorka Aguado joined the performers in producing and transforming video images in real time. Stage designer Javier Larreina created a space especially for the action in this show. 　　 　　Live recording / Grabacion en vivo / Zuzenoko grabaketa 　　“SIRIUS”, live electronics & video.
