Listen to Porter Robinson on iHeartRadio

Porter Robinson is really excited for the release of his album Worlds. The producer has shared a new track from the album called "Sad Machine," on which he makes his vocal debut! 

He explains the track on Twitter as a duet between himself and a robot girl. He explains that he used a Vocaloid which is a synth that "recreates the human singing voice."

Porter tells Fader, "The idea of a duet between a lonely robot girl and the human boy who encounters her occurred to me. I didn't have much time before I had to turn in the entire album, so I just sang the male parts. I wanted something that felt distantly sad, a little cute, surreal, hopeful, and maybe somehow evocative of fiction?"

The single is available now on iTunes.

Porter also revealed the release date to worlds:
