"Novacane" is the debut single by American recording artist Frank Ocean. It was released as the lead single from his mixtape Nostalgia, Ultra. The song was written by Ocean, Tricky Stewart and Victor Alexander, and produced by Stewart. Lyrically, the song narrates a tale of a young female dental student who makes a living doing porn and who recreationally uses local anesthetic drugs that she acquires from her place of study. The song explores themes of isolation, loneliness and a lack of feeling caused by numbness. The song received highly positive reviews from music critics and was listed as one of the best songs of the year by publications such as The New York Times, Spin, Ology, Zimbio and Pitchfork Media. Reviews praised the dark subject matter of the song, and praised Ocean's ability to create narratives and the sonic atmosphere of the track.
