The Flaming Lips’ series of random collaborations rolls on, and their most recent excursion features two interesting guests. The big name guest (in the music world, anyway) is Erykah Badu, who comes in to sing passionately and somewhat seductively over the middle of this mostly-ambient track and in doing so changes the other guest, iPhone’s psyche Siri, from not understanding to understanding. It’s a strange song to say the least, but a rather pleasant one too. Check it out below courtesy of Pitchfork.
