To celebrate the launch of the Audi A3, M.I.A. and Janelle Monáe will respectively perform at private events in New York City and Los Angeles tomorrow. But because we're living in the future, they'll also perform two brand-new duets... via hologram.

According to a press release, it's "the first hologram performance with integrated video mapping." The set "utilizes 3D projection mapping to add layered depth of field perception with animated graphic content, the result of which will be an electric never-before-seen 3D bi-coastal performance."

Translation: Technology will enable them to appear on the same stage at the same time, even though they'll be separated by thousands of miles.
