Björk is no stranger to using technology to express her music in more inventive ways, but now she's using it to shape the music itself in unexpected forms. The Icelandic star is using Microsoft AI as part of Kórsafn ("choral archives"), a non-stop composition playing in the lobby of the Sister City hotel in New York City. The project plays selections from Björk's many choral arrangements (including new ones composed by the Hamrahlid Choir) based on what the AI sees in the sky through a rooftop camera. It'll react based on different cloud types, the behavior of birds, passing aircraft and even barometric pressure. Long-term weather trends will gradually alter the piece, too.
