Update 5/17 2:17 P.M.: Brand New have shared the full version of their latest song, "I Am a Nightmare." The tease didn't lead us astray: this is all classic Jesse Lacey. Listen above.

Original Story 5/17 10:58 A.M.: Last month we outlined a pretty in-depth conspiracy hitting emo internet, one that assumes a final Brand New album is in the works. We all knew this reunion wouldn't last forever, right?

At any rate, the Long Island band has shared a tease of a new song called "I Am a Nightmare." On the track frontman Jesse Lacey sings: "Do I have to die to see the other side? / I am a nightmare and you are a miracle." The latter phrase repeats throughout the chorus. Listen to the snippet here.

It's a high-energy, self-deprecating tune...would we want anything else from Brand New? The full version of the song will drop Friday, May 20.
