StellarScape is an immersive multimedia performance synthesizing music, science, visual art, and technology. The performance includes live musicians, sensors, electronic music, and dance, collaborating through interactive cinematography. The result combines kinesthetic and acoustic sensing with astrophysical simulations of star formation, in real time. This convergence research collaboration is catalyzed by the union of concepts at the confluence of astronomy, humanity, artistic expression through music and dance, and socio-technical experience. This paper summarizes the motivation for the project, the interdisciplinary collaboration required to execute it, goals for the audience experience, early results of the first performances, and ways the piece can be delivered in the future for entertainment, outreach, and education.
